Background
The field of chemical sensor technology has long sought methods to accurately detect and measure molecular presence and concentration in various environments. A pervasive challenge has been developing sensors that can selectively recognize specific molecules in complex mixtures. Traditional sensors often struggle with non-specific binding, resulting in false positives and limited selectivity. They may also suffer from signal degradation over time or under changing environmental conditions, impairing their reliability and long-term usability.
Technology description
Recognitive hydrogels leveraging molecularly imprinted polymers (MIPs) feature bespoke binding cavities attuned to specific triggering molecules, integrated with conductive polymers for enhanced functionality. These hydrogels form the basis of sensors that utilize an impedance sensing component to monitor the presence of the target molecule precisely and in real-time. What sets this technology apart is the fusion of MIPs with conductive polymers, allowing for a significant improvement in signal transduction upon binding of the target molecule. Combined with impedance sensing, this design ensures a highly sensitive and selective response, distinguishing it from traditional sensing mechanisms that may lack specificity or sensitivity.
