Ocular drug delivery has seen several advances in the past few decades, with respect to new drugs, improved formulations, targeted delivery, as well as exploration of new routes of drug administration. New materials have been explored for encasing existing drugs, which can enhance treatment by increasing bioavailability, decreasing toxicity, providing better tissue adherence, targeted delivery as well as increased duration of action. The challenges and requirements are different for the anterior and posterior ocular segments. This review summarizes the recent advances in sustained ocular therapy, both to the anterior and posterior segments, which have been made possible, thanks to nanotechnology. We also discuss the distribution and fate of these nanocarriers themselves, postadministration, as well as clearance from ocular tissues.

Nano-diamino-tetrac (NDAT) targets a receptor on integrin αvβ3; αvβ3 is generously expressed by cancer cells and dividing endothelial cells and to a small extent by nonmalignant cells. The tetrac (tetraiodothyroacetic acid) of NDAT is covalently bound to a poly(lactic-co-glycolic acid) nanoparticle that encapsulates anticancer drugs. We report NDAT delivery efficiency of cisplatin to agent-susceptible urinary bladder cancer xenografts.

Our goal was to improve treatment outcomes for visceral leishmaniasis by designing nanocarriers that improve drug biodistribution and half-life. Thus, long-acting mannose-anchored thiolated chitosan amphotericin B nanocarrier complexes (MTC AmB) were developed and characterized.

International Conference on Nanopore Technology (Shenzhen), 30 March-1 April 2017, Shenzhen, China The International Conference on Nanopore Technology (Shenzhen) was held from 30 March to 1 April 2017 in Shenzhen, China. The goal of the meeting was threefold: leverage the unique properties of nanopore technology to promote transformative advances in medicine, encourage cross-disciplinary collaborations in the research community within China and abroad; and discuss critical challenges that need to be addressed to rapidly advance the field. The meeting was chaired by Peixuan Guo, Endowed chair professor and Director of The Center for RNA Nanobiotechnology & Nanomedicine at The Ohio State University, USA and co-chaired by Xian-En Zhang, distinguished professor of the Institute of Biophysics, Chinese Academy of Sciences, China. The conference was attended by more than 300 academic researchers, hospital administrators, government leaders and scientists from many disciplines across the country from both academic institutions and industry.
