Gelatin-Enabled Microsensor for Pancreatic Trypsin Sensing
Digestive health is critically dependent on the secretion of enzymes from the exocrine pancreas to the duodenum via the pancreatic duct. Specifically, pancreatic trypsin is a major protease responsible for breaking down proteins for absorption in the small intestine. Gelatin-based hydrogels, deposited in the form of thin films, have been studied as potential sensor substrates that hydrolyze in ...
متن کاملModeling and Simulation of Isfet Microsensor for Different Sensing Films
Electronic circuit simulation programs like SPICE have built-in models for semiconductor devices like MOSFET and BJT. However, they do not provide models for electrochemical sensors like ISFETs (Ion-Sensitive Field-Effect Transistors). This paper presents a behavioral macromodel for ISFET-based pH-sensors implemented using PSPICETM. The macromodel is then utilized to present a comparative analy...
متن کاملInductively coupled microsensor networks: relay enabled cooperative communication and localization
In this thesis, we study a novel paradigm for wireless sensor networks: we envision a dense microsensor network, consisting of hundreds or thousands of highly miniaturized wireless nodes with millimeter or sub-millimeter dimensions. Such a microsensor network has many interesting applications ranging from in vivo medical sensing to environmental monitoring. However, the design and operation of ...
متن کاملComparative Hydrolysis of Gelatin by Pepsin, Trypsin, Acid, and Alkali
A comparison has been made of the relative velocity of hydrolysis of the various peptid linkings of the gelatin molecule when hydrolyzed by acid, alkali, pepsin or trypsin. It has been found that: 1. Those linkages which are most rapidly split by pepsin or trypsin are among the more resistant to acid hydrolysis. 2. Those linkages which are hydrolyzed by pepsin are also hydrolyzed by trypsin. 3....
متن کاملGenetic dissection of pancreatic trypsin inhibitor.
In a previous study, a genetic screening procedure was used to identify variants of bovine pancreatic trypsin inhibitor that can fold to an active conformation but that are inactivated much more rapidly than the wild-type protein in the presence of dithiothreitol (DTT). The mechanisms by which 30 of these DTT-sensitive variants are inactivated have now been investigated. Some of the amino acid ...
