About this collection
This themed issue on polymeric biomaterials for cancer nanotechnology is Guest Edited by Jianjun Cheng (University of Illinois at Urbana-Champaign, USA) and Suzie Pun (University of Washington, USA).
Polymeric biomaterials have been extensively used in nanomedicine formulations for cancer therapy. Preclinical and clinical studies have in general revealed that polymeric nanocarriers, when used for chemotherapeutic drug delivery, reduce systemic toxicity and thus mitigate adverse side effects of the drug. In order to continue and even improve on the clinical progress of polymeric anticancer drug formulations, new innovations and discoveries are being made in the following areas: (i) expanding the available suite of polymeric biomaterials that can be reproducibly and controllably manufactured at a suitable scale, (ii) designing carriers with improved biodistribution to tumor sites, (iii) increasing tumor distribution and penetration of polymeric nanocarriers, and (iv) controlling efficient drug release at a desired location and with optimal kinetics. This themed issue contains reviews and research articles in each of these areas. In addition, new advances in polymeric nanobiomaterials for both small molecule chemotherapeutics and anticancer nucleic acids are included.
