Responsive polymer conjugates for drug delivery applications: recent advances in bioconjugation methodologies
2019
AbstractProtein–polymer conjugates have achieved tremendous attention in the last few years, since their importance in diverse fields including drug delivery, biotechnology and nanotechnology. Over the past few years, numerous chemical strategies have been developed to conjugate different synthetic polymers onto proteins and great progress has been made. Currently, there are a handful of therapeutic polymer conjugates that have been approved by the FDA, while many hundreds of products are under extensive clinical trials and preclinical development phases. In this way, the development of novel techniques for conjugation, especially living radical polymerisation (LRP) has greatly enhanced the potential to broaden the scope of therapeutic conjugates. As a consequence, versatile techniques have developed, such as the ‘grafting from’ approach, which allows modifications of biomacromolecules at the atomic level, and subsequently preparing well-defined stimuli-responsive conjugates. These strategies present a un...
