Stimuli-responsive nanoparticles (NPs) based on sustainable polymeric feedstock still need more exploration in comparison with NPs based on synthetic polymers. In this report, stimuli-responsive NPs from novel ionic cellulose derivatives were prepared via a facile nanoprecipitation. Cellulose 10-undecenoyl ester (CUE) with a degree of substitution (DS) of 3 was synthesized by esterification of ...

Nanotechnology is a straightforward strategy for the development of drug delivery systems. Poly(caprolactone) (PCL) has been used as a hydrophobic biodegradable polymeric core of nanoparticles for encapsulation of various kinds of self-problematic drugs. In this study, PCL was fabricated by ring opening polymerization and the nanoparticles were then obtained by solvent diffusion and evaporation...

Nanoparticles were obtained by nanoprecipitation and emulsion solvent evaporation (ESE) method. In the ESE method, size of particles depended on type concentration surfactant (in water phase) polymer organic phase). The best results with ionic surfactants, however, use such compounds may accelerate degradation process polymers. ratio (methylene chloride) to non-solvent (hexane) has a significan...

Zein-based nano/microparticles have been demonstrated to be promising carrier systems for both the food industry and biomedical applications. However, the fabrication of size-controlled zein particles has been a challenging issue. In this study, a modified anti-solvent precipitation method was developed, and the effects of various factors, such as mixing method, solvent/anti-solvent ratio, temp...

in this paper, a boussinesq equation is solved by using the adomian's decomposition method, modified adomian's decomposition method and homotopy analysis method. the approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relation. the existence and uniqueness of the solution and the convergence of the propose...

Hydroxypropyl starch was synthesized by modified sago starch with hydroxypropylation reaction. Hydroxypropyl starch nanoparticles with mean particle sizes of 110 nm are obtained by controlled precipitation through the drop-wise addition of dissolved hydroxypropyl starch solution into excess absolute ethanol. Piperine was loaded onto hydroxypropyl starch nanoparticles and native starch nanoparti...

We report the use of microfluidic rapid mixing using hydrodynamic flow focusing to control the self-assembly of polymeric nanoparticles (NPs) that can be used for drug delivery. PLGA-PEG polymeric NPs and PLGA-lipid hybrid NPs were synthesized through nanoprecipitation—a process that involves dilution of a block copolymer from a solvent to an anti-solvent resulting in the precipitation of NPs. ...
