A simple method is developed to construct anticoagulant surfaces via passive adsorption of heparin onto the protonated plasma-polymerized allylamine (PPAam) films from phosphate-buffered saline (PBS). These protonated PPAam surfaces are found to have high affinity to heparin. Importantly, the heparin-functionalized

Systematic studies of silver particle deposition kinetics under diffusion transport on poly(allylamine hydrochloride) (PAH) modified mica were carried out. Monolayer coverage, quantitatively determined by AFM and SEM, was regulated within broad limits by adjusting the deposition time and the ionic

Fluorescent-magnetic-biotargeting multifunctional microcapsules (FMBMMs) are designed and fabricated via layer-by-layer assembly. It is found that the arginine-glycine-aspartate-modified FMBMMs were capable of sensitively detecting and efficiently isolating approximately 80% target cancer cells within 20 min. More importantly, FMBMMs present a general

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
