666 results about "Adenosine triphosphate" patented technology

Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. When consumed in metabolic processes, it converts either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP). Other processes regenerate ATP so that the human body recycles its own body weight equivalent in ATP each day. It is also a precursor to DNA and RNA, and is used as a coenzyme.

Sensor preparation method based on ECL-RET action between GO and GQDs and application on kinas detection

The invention discloses a sensor preparation method based on an ECL-RET action between GO and GQDs and an application on kinas detection, and belongs to the field of electrochemiluminescence (ECL). The preparation method comprises the following steps: coating chitosan on the surface of an electrode, and orderly assembling graphene quantum dots and polypeptides onto the surface of the electrode through a covalent interaction. Under the actions of protein kinase and triphosadenine, the polypeptides carry out phosphorylation reactions, through the specific recognition action between an antibody and an antigen, oxidized graphene conjugated with a phosphorylated antibody is assembled to the phosphorylated serine sites of the polypeptide, thus the distance between the oxidized graphene and the graphene quantum dots is narrowed down, so that the electrochemiluminescence (ECL) of graphene quantum dots is quenched. The larger the concentration of protein kinase is, the more phsophorylated sites are generated on the polypeptide modified electrode surface, the more oxidized graphene is assembled on a sensing interface, the stronger the electrochemiluminescence quenching effect of graphene quantum dots will be, and thus the high sensitive detection on protein kinase is achieved.

Detection of Analytes in Samples Using Liposome-Amplified Luminescence and Magnetic Separation

The invention relates to the encapsulation of luminescence-related molecules, including but not limited to, adenosine triphosphate (ATP), adenylate kinase (AK), alkaline phosphatase (ALP), luminol and luciferin / luciferase cocktails, within liposomes. These liposomes can be employed to enhance the luminescence detection of microorganisms and compounds in various products and samples. The liposomes containing the luminescence-related molecules can bear a probe which has a specific sequence or structure that, in turn can be used to hybridize to, or couple with, a portion of the target analyte. Within the same assay, paramagnetic beads can bear a probe having a specific sequence or structure that, can hybridize to, or couple with, a second portion of the target analyte to create a complex of analyte bound to paramagnetic beads and liposomes. This type of assay can be often referred to as a ‘sandwich’ assay. Once the probes hybridize to, or couple with, their targets, a complex can be formed of the paramagnetic beads, the analyte, or portion thereof, and the liposomes. This complex can then be washed to remove those components that are non-hybridized or non-coupled. Then, the paramagnetic bead-analyte-liposome complexes can be isolated from the sample using magnetic separation techniques and can be treated so as to release their encapsulated ATP, AK or other luminescence-related compounds. The resulting luminescence can then be determined in a chemical assay. This determination can be qualitative (i.e., an absence / presence assay) or quantitative (i.e., which can measure a specific amount of analyte present). Through the use of a cocktail of probe types, the assay can also qualitatively or quantitatively measure the presence of more than one analyte simultaneously. This type of assay can be of commercial importance in clinical and forensic applications, the personal care, pharmaceutical, food and beverage markets, as well as in environmental sample assays.

Core-shell type ultra-micro electrode prepared through coaxial electrostatic spinning and preparation method thereof

The invention relates to a preparation method and application of a core-shell type ultra-micro electrode. The core-shell structure ultra-micro electrode is obtained by preparing ultra-micro electrode fibers of a coaxial structure in a one-step mode through a coaxial electrostatic spinning method and then performing packaging. The coaxial structure comprises a core electrode base layer and one or two surface sensing layers. By the adoption of the one-step forming technology, the complex surface modification process of traditional ultra-micro electrodes (such as glassy carbon electrodes obtained after ablation treatment) is omitted, and the ultra-micro electrode with the diameter ranging from 40 nm to 6 micrometers can be prepared; due to the subsequent treatment temperature ranging from 70 DEG C to 150 DEG C, the structures and functions of organic functional components (such as biological protein and enzymes) in a modification layer of the ultra-micro electrode can be easily maintained, which is of great significance for the pluralistic design of the ultra-micro electrode. The ultra-micro electrode is used for detecting adenosine triphosphate (ATP), dopamine and adrenal hormones and is high in response speed and sensitivity, strong in anti-jamming capability and especially suitable for on-line rapid determination, particularly, real-time non-destructive determination of living cells.

The invention relates to medicine, more precisely to hygieology and ophthalmology, and can be used for preventing deterioration of the sense of sight and also for improving the sense of sight of users reading off a screen. The invention increases the level of comfort and the reliability of the inventive method. The inventive method consists in influencing the user's eyes by additional pictures on screen, whereby an image is formed whose shape and color have a relaxing effect on a visual analyzer. The duration of exposure of the additional pictures is organized in such a way that makes it possible to restore the content of adenosine triphosphate and oxygen in the eye tissue; time intervals between exposures is less than time needed for acidulation of tissues and for the occurrence of a lack of oxygen. In the beginning the user watches such additional pictures whose shape and color range have a relaxing reflect on the visual analyzer region in the central nervous system (CNS). The shape and the color range of the additional pictures which have a relaxing effect on the visual analyzer are selected in such a way that they perform a relaxing effect on lateral and transversal eye muscles. The time interval between the images ranges from 20 to 150 min, the duration of exposure is selected within a range of 1.0 to 6.0 min. Together with the relaxing effect on a visual organ, said relaxing action is also exerted on an organ of hearing and muscles of the neck. The shape of at least a part of the additional pictures is smooth and roundish without distinct lines and boundaries.
