[Chem. Commun.] Nucleic Acid-Mediated Gold Oxidation: Novel Biolithography for Surface Microfabrication and New Insight on Gold-Based Biomaterials
In Nature, certain organisms can perform microbial corrosion on base metals by oxidation of neutral metallic atoms (H. L. Ehrlich, Appl. Microbiol. Biotechnol., 1997). Herein we describe the first discovery of biological nucleic acids able to catalyze and mediate gold oxidation from neutral Au(0) to trivalent Au(iii) under certain oxidative environments provided by mild oxidizing reagent N-bromosu...

Bio-based green composites with high performance from poly(lactic acid) and surface-modified microcrystalline cellulose
ABSTRACT: Bio-based green composites with high performance were prepared from poly(lactic acid) (PLA) and microcrystalline cellulose (MC) fibers grafted with L-lactic acid oligomers (g-MC). The chemical structure of g-MC was characterized by FTIR and NMR methods, which indicate that L-lactic acid oligomers were successfully grafted onto microcrystalline cellulose. The grafting percentage of L-la...

Targeting and anti-tumor effect of folic acid-labeled polymer–Doxorubicin conjugates with pH-sensitive hydrazone linker
Multifunctional micelles were successfully prepared by co-assembling a Doxorubicin-conjugated
copolymer (mPEG-b-P(LA-co-ME/Dox), for antitumor properties) and a Rhodamine B-conjugated
copolymer (mPEG-b-P(LA-co-ME/RhB), for imaging) with a folic acid (FA)-conjugated copolymer
(FA-PEG-b-PLA, for targeting), respectively. DLS showed that the sizes of these micelles were in the
range of 150–300 n...

Synthesis and characterization of novel biotinylated biodegradable poly(ethylene glycol)-b-poly(carbonate-lactic acid) copolymers
Poly(ethylene glycol)-b-poly(5-benzyloxy-trimethylene carbonate-lactic acid) copolymers (PEG-b-P(BTMC-LA)) were synthe-
sized by ring-opening polymerization of lactide and 5-benzyloxy trimethylene carbonate in the presence of mono-hydroxyl poly(eth-
ylene glycol) with diethyl zinc as catalyst. They were further converted into deprotected copolymers with the pendant hydroxyl
groups by hydrogenol...

A Novel Poly(L-glutamic acid) Dendrimer Based Drug Delivery System with Both pH-Sensitive and Targeting Functions
The functionalization of pH-sensitiveness and cellular targeting is a promising strategy to fabricate drug delivery systems with high efficiency, high selectivity and low toxicity. In this paper, a poly(L-glutamic acid) dendrimer based drug delivery system with both pH-sensitive and targeting functions is reported. Poly(L-glutamic acid) dendrimers with a polyhedral oligomeric silsesquioxane (POSS)...

Regulation of endothelial cells migration on poly(D, L-lactic acid) films immobilized with collagen gradients
To investigate the effect of protein surface-density gradient on the motility of endothelial cells, we developed a novel approach for the fabrication of a collagen density gradient onto poly(D,L-lactic acid) (PDLLA) films in this study. The approach involves a sequential alkali hydrolysis of PDLIA films to produce a density gradient of -COOH moieties onto the films, which were activated and then c...
