Integrated microfluidic sensing chip and method for detecting microfluid

The invention discloses an integrated microfluidic sensing chip and a method for detecting microfluid. The integrated microfluidic sensing chip comprises a rigid polymer substrate, a polydimethylsiloxane circulating layer and a surface plasma resonance sensing sheet. Tested objects flow through a filter micro column of a filter passage of the polydimethylsiloxane circulating layer to be filtered and separated, and the tested objects which do not pass through the filter micro column enter a waste liquid passage and are discharged from a waste liquid outlet. The tested objects which pass through the filter micro column separation enter a sensing detection passage of the chip to react with specific biological molecules on the surface plasma resonance sensing sheet, and the surface plasma resonance sensing sheet carries out labeling-free and real-time quantitative detection for the biochemical reaction on the chip. The method integrates sample filtration and pretreatment, separation and labeling-free sensing detection, and has the characteristics of high integration degree, simple operation, high detection sensitivity, labeling prevention and little sample consumption. The integrated microfluidic sensing chip and the method are suitable for clinical diagnosis and analysis for body fluid containing complex components such as blood, urine, spit and the like.

System for abnormal data identification based on merging unit

ActiveCN106896338AQuickly judge output data exceptionsPrevent erroneous logical judgmentsElectrical measurementsPhase currentsSampling instant
The present invention discloses a system for abnormal data identification based on a merging unit. The system comprises a mutual inductor, a collector and a merging unit. The mutual inductor collects one-time current and voltage data, performs integration conversion to form digital quantity and transmits the digital quantity to the collector; the merging unit receives sampling data sent from the collector, performs protocol conversion and sends the sample data to a protective device; and the merging unit receives sample instant data of the collector and calculated adjacent sample point instant difference of phase current and phase voltage in real time, regulates the maximum sampling value of the last cyclic wave in real time through each cyclic wave according to the sampling cyclic wave amplitude and the sampling frequency of the message sent by the collector, and repeatedly calculates the mutation threshold value according to the value, determines whether the adjacent sampling point instant difference value exceeds the mutation threshold value or not, reports the sample abnormality when the instant difference value exceeds the mutation threshold value and marks the sampling points having the instant difference value exceeding the mutation threshold value as the mutation value. The system for abnormal data identification based on the merging unit can rapidly determine the abnormal data output by the collector so as to avoid logic misjudgement of a transformer station protection control device.

Active near infrared fluorophore as well as preparation method and application thereof

The invention belongs to the field of molecular imaging reagents ad relates to an active near infrared fluorophore for rapidly marking bioactive molecules. A general formula of the active near infrared fluorophore is IRP-B-NHS, wherein IRP is an anthocyanin near infrared fluorophore; B is an aromatic group introduced to the secondary position of the anthocyanin fluorophore by virtue of a carbon-carbon bond; NHS is N-hydroxysuccinimide eater. A preparation method of the active near infrared fluorophore comprises the following steps: with the anthocyanin fluorophore as a parent, introducing benzene carboxylic acid into the fluorophore by virtue of the carbon-carbon bond through Suzuki-Miyaura reaction, modifying phenyl carboxylic acid to produce the N-hydroxysuccinimide eater, reacting with primary amine in a biomolecule under the physiological condition, and marking the biomolecule with the near infrared fluorophore to realize noninvasive tracing. The active near infrared fluorophore is capable of rapidly, safely, effectively and stably marking the bioactive molecules including polypeptide, proteins, antibodies or polymer molecules and has important significance of noninvasively monitoring and quantifying distribution of target active molecules in vivo.
