Polymeric biomaterials for biophotonic applications

With the growing importance of optical techniques in medical diagnosis and treatment,there exists a pressing need to develop and optimize materials platform for biophotonic applications.Particularly,the design of biocompatible and biodegradable materials with desired optical,mechanical,chemical,and biological properties is required to enable clinically relevant biophotonic devices for translating in vitro optical techniques into in situ and in vivo use.This technological trend propels the development of natural and synthetic polymeric biomaterials to replace traditional brittle,nondegradable silica glass based optical materials.In this review,we present an overview of the advances in polymeric optical material development,optical device design and fabrication techniques,and the accompanying applications to imaging,sensing and phototherapy.
