Development of urea biosensor using polymer technologies for blood and urine tests

Based on polymeric nanotechnologies, enzyme sensors and microreactors have been developed that can determine urea in liquids. It is shown that urea biosensor is able to work for a long time (up to 2 months) without significant loss of enzyme activity. Polymer technology for manufacturing sensors is less laborious and expensive compared to other similar technologies. We propose to develop biosensor devices - urea analyzers with polymer enzyme chips for express diagnostics of biological fluids (blood, urine).
