Surface-immobilization of molecules for detection of chemical warfare agents

Abstract

Fabrication of nanoscale molecular assemblies with advanced functionalities is an emerging field. These systems provide new perspectives for the detection and degradation of chemical warfare agents (CWAs). The main concern in this context is the design and fabrication of "smart surfaces" able to immobilize functional molecules which can perform a certain function or under the input of external stimuli. This review addresses the above points dealing with immobilization of various molecules on different substrates and describes their adequacy as sensors for the detection of CWAs.
