The artificial binding proteins are much smaller than antibodies usually less than 1.They are thus especially suitable to create biosensors.Enzymatic interactionseditThe specific binding capabilities and catalytic activity of enzymes make them popular bioreceptors.Analyte recognition is enabled through several possible mechanisms 1 the enzyme converting the analyte into a product that is sensor detectable, 2 detecting enzyme inhibition or activation by the analyte, or 3 monitoring modification of enzyme properties resulting from interaction with the analyte.The main reasons for the common use of enzymes in biosensors are 1 ability to catalyze a large number of reactions 2 potential to detect a group of analytes substrates, products, inhibitors, and modulators of the catalytic activity and 3 suitability with several different transduction methods for detecting the analyte.Notably, since enzymes are not consumed in reactions, the biosensor can easily be used continuously.The catalytic activity of enzymes also allows lower limits of detection compared to common binding techniques.However, the sensors lifetime is limited by the stability of the enzyme.Affinity binding receptorseditAntibodies have a high binding constant in excess of 1.Lmol, which stands for a nearly irreversible association once the antigen antibody couple has formed. Progress Bar Update Vb Net . For certain analyte molecules like glucose affinity binding proteins exist that bind their ligand with a high specificity like an antibody, but with a much smaller binding constant on the order of 1.Lmol. The association between analyte and receptor then is of reversible nature and next to the couple between both also their free molecules occur in a measurable concentration.In case of glucose, for instance, concanavalin A may function as affinity receptor exhibiting a binding constant of 4x.Lmol. 1. 4 The use of affinity binding receptors for purposes of biosensing has been proposed by Schultz and Sims in 1.L. 1. 6 The sensor principle has the advantage that it does not consume the analyte in a chemical reaction as is occurs in enzymatic assays.Nucleic acid interactionseditBiosensors that employ nucleic acid interactions can be referred to as genosensors.The recognition process is based on the principle of complementary base pairing, adenine thymine and cytosine guanine in DNA.If the target nucleic acid sequence is known, complementary sequences can be synthesized, labeled, and then immobilized on the sensor.The hybridization probes can then base pair with the target sequences, generating an optical signal.The favored transduction principle employed in this type of sensor has been optical detection.EpigeneticseditIt has been proposed that properly optimized integrated optical resonators can be exploited for detecting epigenetic modifications e.DNA methylation, histone post translational modifications in body fluids from patients affected by cancer or other diseases.Photonic biosensors with ultra sensitivity are nowadays being developed at a research level to easily detect cancerous cells within the patients urine.Different research projects aim to develop new portable devices that uses cheap, environmentally friendly, disposable cartridges that require only simple handling with no need of further processing, washing, or manipulation by expert technicians.OrganelleseditOrganelles form separate compartments inside cells and usually perform function independently.Different kinds of organelles have various metabolic pathways and contain enzymes to fulfill its function.Commonly used organelles include lysosome, chloroplast and mitochondria.The spatial temporal distribution pattern of calcium is closed related to ubiquitous signaling pathway.Mitochondria actively participate in the metabolism of calcium ions to control the function and also modulate the calcium related signaling pathways.Experiments have proved that mitochondria have the ability to respond to high calcium concentration generated in the proximity by opening the calcium channel.In this way, mitochondria can be used to detect the calcium concentration in medium and the detection is very sensitive due to high spatial resolution.Another application of mitochondria is used for detection of water pollution.Detergent compounds toxicity will damage the cell and subcellular structure including mitochondria.
