Sensing with nano engineered plastics
Abstract:
A family of sensors has been developed that uses polymer films with moulded apertures that allow particular molecules to fit into them.
Initially developed to detect water contaminants such as herbicides and algal toxins, they can also be made for larger molecules, such as proteins. This is effected by embossing, as opposed to moulding, and - combined with optical, piezoelectric and electrochemical detection - offers a method of identifying a wide range of chemical molecules.
