Surface roughness plays an important role in determining the mechanical properties, wettability, and self-assembly colloidal systems. In this work, we develop a simple fast method to produce rough SU-8 rods, bananas, spheres, via nanoprecipitation of water. During process, nanospheres are absorbed onto surface particles then cross-linked using UV-light. The size spherical asperities asperity de...

Polystyrene (PS) nanoparticles were prepared via a nanoprecipitation process. The influence of the pH of the buffer solution used during the immobilization process on the loading of Candida antarctica lipase B (Cal-B) and on the hydrolytic activity (hydrolysis of p-nitrophenyl acetate) of the immobilized Cal-B was studied. The pH of the buffer solution has no influence on enzyme loading, while ...

The Gemcitabine loaded PLGA nanoparticles were prepared by modified nanoprecipitation method, to improve the bioavailability of the drug in brain. The nanoparticular formulation was characterized for particle size analysis, encapsulation efficiency, zeta potential and in vitro release study. The pharmacokinetic studies of Gemcitabine-loaded PLGA nanoparticles were carried out in Sprague Dawley ...
