A facile strategy to functionalize gold nanorods with polycation brushes for biomedical applications.

Acta Biomater. 10(8) , 3786-94, (2014)

The fabrication of highly efficient nonviral gene carriers with low cytotoxicity remains a challenge in gene therapy. This paper reports a facile strategy to combine the advantages of gold nanorods (Au NRs) and polycations through surface functionalization. D...

A New Hyaluronic Acid Derivative Obtained from Atom Transfer Radical Polymerization as a siRNA Vector for CD44 Receptor Tumor Targeting.

Macromol. Biosci. 15 , 1605-15, (2015)

Two derivatives of hyaluronic acid (HA) have been synthesized by atom transfer radical polymerization (ATRP), starting from an ethylenediamino HA derivative (HA-EDA) and by using diethylaminoethyl methacrylate (DEAEMA) as a monomer for polymerization. Both sa...

Molecularly imprinted protein recognition thin films constructed by controlled/living radical polymerization.

J. Biosci. Bioeng. 119(2) , 200-5, (2015)

We demonstrated the synthesis of molecularly imprinted polymers (MIPs) with binding affinity toward a target protein, ribonuclease A (RNase) by atom transfer radical polymerization (ATRP) of acrylic acid, acrylamide, and N,N'-methylenebisacrylamide in the pre...

Design and synthesis of digitally encoded polymers that can be decoded and erased.

Nat. Commun. 6 , 7237, (2015)

Biopolymers such as DNA store information in their chains using controlled sequences of monomers. Here we describe a non-natural information-containing macromolecule that can store and retrieve digital information. Monodisperse sequence-encoded poly(alkoxyami...

Multifunctional colloids with optical, magnetic, and superhydrophobic properties derived from nucleophilic substitution-induced layer-by-layer assembly in organic media.

ACS Nano 5(7) , 5417-26, (2011)

We demonstrate the successful preparation of multifunctional silica colloids by coating with 2-bromo-2-methylpropionic acid (BMPA)-stabilized quantum dots (BMPA-QDs) and BMPA-stabilized iron oxide particles (BMPA-Fe(3)O(4)), along with amine-functionalized po...

Synthesis and properties of novel biomimetic and thermo-responsive dextran-based biohybrids.

Carbohydr. Polym. 99 , 728-35, (2014)

A new class of biodegradable, biomimetic and thermo-responsive dextran/synthetic glycopolymer biohybrids (dextran-graft-poly(lactobionamidoethyl methacrylate)-block-poly(di(ethylene glycol) methyl ether methacrylate), dextran-g-(PLAMA-b-PDEGMA)), was synthesi...

Cellular interaction of folic acid conjugated superparamagnetic iron oxide nanoparticles and its use as contrast agent for targeted magnetic imaging of tumor cells.

Int. J. Nanomedicine 7 , 3503-16, (2012)

The purpose of the study was to develop tumor specific, water dispersible superparamagnetic iron oxide nanoparticles (SPIONs) and evaluate their efficacy as a contrast agent in magnetic resonance imaging (MRI). We have developed SPIONs capped with citric acid...
