We review recent progress in polymer-drug conjugate for cancer nanomedicine. Polymer-drug conjugates, including the nanoparticle prepared from these conjugates, are designed to release drug in tumor tissues or cells in order to improve drugs' therapeutic efficacy. We summarize general design principles for the polymer-drug conjugate, including the synthetic strategies, the design of the chemica...

One of the most important required additives in production of composite solid propellants are bonding agents. These compounds are used in order to increase the adhesion between the polymer resin and the oxidizer and also to enhance the physical and mechanical properties and to improve the solids loading of propellants. In some cases, the bonding agents also play a role as a curing agent by cros...

The biocompatible and biodegradable polymer nanofiber with high potential for anti-bacterial coating are used for: multi-functional membranes, tissue engineering, wound dressings, drug delivery, artificial organs, vascular grafts and etc. Electrospinning nanofiber made of scaffolding due to characteristics such as high surface to volume ratio, high porosity and very fine pores are used for a wi...

It is increasingly important that we learn how to fabricate materials in environmentally friendly ways using common resources that are abundant in nature. Biomineralization, the process by which living organisms create a variety of sophisticated composites, such as bone and shell, is an ideal model for such fabrication. This article reviews recent progress toward the synthesis of polymer–inorga...

Polymer-supported O(6)-(benzotriazol-1-yl)inosine derivatives (Pol-I and Pol-dI) have been synthesized reasonably effectively via reaction of nucleoside phosphonium salts with polymer-linked HOBt (Pol-HOBt). In constast to solution chemistry, use of polymer-supported BOP (Pol-BOP) did not lead to efficient nucleoside loading. Presence of the nucleosides on the support could be readily detected ...

Covalently crosslinked polymeric materials which swell, but do not dissolve, in a given solvent (polymer gels) have found utility in a number of applications including tissue engineering, drug delivery, chemical sensing, microfluidics, cosmetics, and microelectronics. End-linked polymer gels (model networks or MNs) are especially promising for drug delivery applications due to their easily cont...
