[0006] International Patent Publications:WO 2017 / 164982 Al 2017 Plaxco et al.TECHNICAL FIELD

[0007] The present disclosure relates to wearable biosensing systems, and more particularly to a multi-modal wearable platform integrating sensing capabilities; hollow microneedle-mediatedAttorney Docket No. 147702-0103interstitial fluid (TSF) sampling, real-time fluid integrity monitoring, electrochemical aptamerbased (EAB) molecular sensing, physiological sensing, environmental sensing, edge-based sensor fusion, a transmitter, and a modular replaceable sensing architecture enabling continuous, minimally invasive biomarker monitoring with cloud-connected artificial intelligence analytics.BACKGROUND

[0008] Chronic and metabolic diseases, including cardiovascular disease, stroke, dementia, Alzheimer's disease, diabetes, obesity, and certain cancers, remain leading causes of morbidity and mortality worldwide. This burden is further compounded by hormonal dysregulation across the human lifespan, including perimenopause, menopause, andropause, postpartum hormonal disruption, fertility disorders, and ovulatory dysfunction, each characterized by dynamic biochemical fluctuations that are not adequately captured by existing monitoring approaches. Conventional diagnostic methods, including laboratory-based blood and urine assays, provide only episodic measurements that are temporally insufficient to capture rapid or transient changes in biomarker concentrations. Existing continuous monitoring devices are generally limited to single-analyte detection using enzymatic sensing architectures and have not been extended to multi-analyte panels spanning hormonal, metabolic, and inflammatory biomarkers.

[0009] No prior wearable continuous monitoring system is known to integrate electrochemical aptamer-based sensing of multiple analytes, including but not limited to estradiol, progesterone, testosterone, luteinizing hormone, and follicle-stimulating hormone with real-time verification of biological fluid transport conditions and end-to-end artificial intelligence analytics. In particular, existing systems lack a dedicated fluid integrity monitoring subsystem configured to compute a transport integrity score representing physical fluid transport conditions and to apply that score as a confidence weight to individual analyte measurements to produce validated analyte outputs. Nor do existing systems provide integrated architectures capable of generating individualized hormonal cycle phase determinations, predictive risk trajectories, and personalized behavioral recommendations from a single continuous biological fluid access point.

[0010] Accordingly, a need exists for an integrated, continuous multi-analyte biosensing platform that combines aptamer-based molecular sensing, real-time fluid transport integrity monitoring, and Al-driven analytics to enable reliable, longitudinal monitoring of hormonal,Attorney Docket No. 147702-0103metabolic, and inflammatory biomarkers. Such a system would support improved detection, prediction, and management of chronic disease risk, hormonal health, and metabolic dysfunction across the human lifespan.BRIEF SUMMARY

[0026] Embodiments of the present disclosure, the hollow microneedle array 202 may comprise one or more hollow microneedles configured to penetrate a tissue interface of a subject and access a biological fluid. In certain embodiments, the microneedle array may comprise one or more microneedles selected from hollow microneedles, hollow-bore microneedles, porous microneedles 224, coated microneedles, solid microneedles, or hybrid combinations thereof, configured for biological fluid access, transport, sensing, or drug delivery.

[0030] Electrochemical Aptamer-Based Sensors.

[0031] FIGS. 3A and 3B is a schematic diagram illustrating an EAB sensor configuration 300 in accordance with embodiments of the present disclosure. The molecular sensing module 206 may comprise one or more EAB sensors 302 disposed on one or more functionalized electrodes 304, each individually addressable and functionalized with a biorecognition element specific to a different target analyte, with shared or per-electrode counter 306 and reference electrodes 308.

EAB sensors may support electrochemical regeneration wherein an applied potential waveform dissociates bound analyte from the biorecognition element after each measurement cycle, restoring the sensor to its unbound baseline state and enabling continuous monitoring over an intended wear period.

[0034] Embodiments of the present disclosure, the molecular sensing module may be configured to detect two or more analytes in the biological fluid simultaneously from a single biological fluid sample. Target analytes may include but are not limited to glucose, estradiol, progesterone, testosterone, cortisol, lactate, C-reactive protein, beta-amyloid, carboxyhemoglobin, prostatespecific antigen (PSA), tumor necrosis factor-alpha (TNF-alpha), p-tau217, luteinizing hormone (LH), follicle-stimulating hormone (FSH), or any other species detectable by a biorecognition element, or any combination thereof. Analytes may be selected from one or more of the following categories: hormonal analytes, metabolic analytes, inflammatory analytes, neurological analytes, or oncological analytes, or any combination thereof.

[0035] Embodiments of the present disclosure, the scalable analyte panel of the molecular sensing module may comprise any two or more analytes detectable by one or more electrochemical aptamer-based sensors of the platform, without limitation to the specific analytes enumerated herein. The analytes detectable by the platform include, but are not limited to: metabolic analytes such as glucose, lactate, ketones, urea, creatinine, uric acid, triglycerides, cholesterol, and aminoAttorney Docket No. 147702-0103acids; hormonal analytes such as estradiol, progesterone, testosterone, cortisol, luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), insulin, glucagon, growth hormone, dehydroepiandrosterone (DHEA), and melatonin; inflammatory analytes such as C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8), cytokines, tumor necrosis factor-alpha (TNF-alpha), procalcitonin, and fibrinogen; neurological analytes such as beta-amyloid, p-tau217, alpha-synuclein, neurofilament light chain (NIL), and brain-derived neurotrophic factor (BDNF); oncological analytes such as prostate-specific antigen (PSA), carcinoembryonic antigen (CEA), cancer antigen 125 (CA-125), and circulating tumor DNA; pharmacological analytes such as vancomycin, tobramycin, doxorubicin, irinotecan, and therapeutic drug metabolites; and any other analyte for which a specific aptamer-based biorecognition element has been or can be identified using SELEX or equivalent in vitro selection processes, or any combination thereof.

[0036] Embodiments of the present disclosure, the identity and number of analytes comprising the scalable analyte panel may be selected based on the target disease domain, subject population, clinical application, or operational context, without departing from the scope of the claimed invention.

The foregoing enumeration of analytes and application domains is illustrative and not limiting, and additional analytes and application domains are within the scope of the present disclosure as aptamer-based biorecognition elements for additional analyte targets continue to be identified and validated.

[0037] Embodiments of the present disclosure, the EAB sensor architecture operates according to a unified physical and chemical principle that is predictably applicable across a broad range of target analytes. The unifying principle enables one of ordinary skill in the art to construct an EAB sensor for any analyte for which a specific binding aptamer has been identified or can be identified using known aptamer selection methods, without undue experimentation. The predictability of thisAttorney Docket No. 147702-0103principle across diverse analyte classes — including small molecule metabolites such as glucose and cortisol, hormones such as estradiol and testosterone, proteins such as C-reactive protein and prostate-specific antigen, and neurological biomarkers such as beta-amyloid and p-tau217 — has been established in the scientific literature and is within the ordinary skill of the art. Accordingly, the phrase "two or more electrochemical aptamer-based sensors" as used in the appended claims encompasses EAB sensors configured to detect any two or more analytes for which specific binding aptamers have been or can be identified, and is not limited to the specific analyte examples enumerated herein. EAB sensors are structurally and mechanistically distinct from enzymatic biosensors used in prior art continuous glucose monitoring and multi-analyte wearable sensing systems; the specific electrode surface chemistry, aptamer functionalization, redox reporter attachment, and electrochemical interrogation protocol of EAB sensors are not interchangeable with enzymatic sensor architectures and cannot be combined with hollow microneedle microfluidic systems used in prior enzymatic sensing platforms without substantial redesign beyond ordinary skill.

[0038] Fluid Integrity Monitoring Subsystem.

[0039] FIG. 4 is a schematic diagram illustrating the FIMS 400 in accordance with embodiments of the present disclosure. The FIMS 400 comprises at least two flow detection electrode pairs 402 disposed distally 408 and proximally 410 at spaced positions along the microfluidic layer 204, a flow rate computation module 404, and a fault classification module 406. Transport of biological fluid 414 by a water-absorbing polymer with one or more passive osmotic pumps 412 via one or more vents 312 through one or more microneedles 201.

[0040] Embodiments of the present disclosure provide that the fluid integrity monitoring subsystem (FIMS) computes a real-time biological fluid flow rate 404 based on transit time between a proximal 410 and distal electrode 408 pair 402 and determines a transport integrity score (TIS) as a continuous variable derived from one or more parameters including measured flow rate, flow rate variability, impedance characteristics, and time since a last validated flow event. The FIMS may further classify fault conditions including but not limited to low-flow, noflow, high-flow, and flow instability, each associated with one or more of microneedle clogging, biofouling, air-lock, tissue delamination, improper insertion depth, or microvascular breach. TheAttorney Docket No. 147702-0103TIS may be used by a sensor fusion algorithm, with or without Al integration, as a confidence weight applied to one or more analyte readings, wherein analyte measurements obtained during periods of reduced transport integrity are assigned proportionally lower confidence weights or withheld from reporting pending restoration of fluid flow.

[0041] Embodiments of the present disclosure, the transport integrity score computed by the FIMS represents a hardware-anchored, physical measurement of biological fluid transport conditions within the microfluidic layer 204 and is not equivalent to software-based signal quality metrics or mathematical corrections applied by a general -purpose processor. The application of the transport integrity score as a confidence weight to individual analyte measurements, producing a validated analyte output, constitutes a physical hardware-integrated data validation mechanism not present in prior art wearable biosensors. This architecture provides a technical improvement to wearable biosensor reliability that is not achievable by abstract data processing or by biosensing systems lacking a dedicated fluid transport monitoring subsystem.

[0042] Modular Replaceable Sensing Architecture.

[0043] FIG. 5 is a block diagram illustrating the MRSA 500 in accordance with embodiments of the present disclosure. The MRSA 500 comprises a reusable command module 502 and one or more removable sensing modules 504. The reusable command module 502 may contain an edge processor 506, a wireless communication module 508, a power management module 510, nonvolatile memory 512, amplifier 536, and a module interface 514, or any combination thereof. Each body interface sensing layers 504 may comprise at least one of a molecular sensing layer 516 comprising one or more EAB sensors configured to detect one or more analytes 530 in a biological fluid accessed through a hollow microneedle array, an optical sensing layer 518 comprising one or more photoplethysmographic sensors configured to measure physiological parameters of the subject, an environmental sensing module 520 comprising one or more chemical or physical threat detection elements 534, or a drug delivery module 522 comprising one or more therapeutic delivery ports and microfluidic pathways that may be configured to deliver one or more therapeutic agents through or adjacent to a body interface module 532, or a bioelectrical impedance analysis 526 configured to apply an alternating electrical current at one or more frequencies to a tissue interface of a subject and to measure resulting impedance to generate one or more of a bodyAttorney Docket No. 147702-0103composition estimate, a hydration status estimate, or a phase angle measurement, or any combination thereof.
