We propose and demonstrate a scheme for optical nanoparticle characterization, optofluidic force induction (OF2i), which achieves real-time counting with single-particle sensitivity, high throughput, particle sizes ranging from tens of nanometers to several micrometers. The particles be analyzed flow through microfluidic channel alongside weakly focused laser vortex beam, accomplishes two-dimen...
Abstract The mechanical properties of carbon fiber-reinforced epoxy composites were identified by adding carbon-based nano-reinforcements, such as multi-wall nanotubes (CNTs) and graphene platelets (GP), into the matrix conducting suitable experiments. main focus this study is to compare tensile modulus, strength, flexural thermal conductivity with nanoparticle reinforcement. results revealed t...
Background: Chitosan is a biodegradable, biocompatible polymer regarded as safe for human dietary. Nanoparticles (NP) prepared with chitosan derivatives typically possess a positive surface charge and mucoadhesive properties such that can adhere to mucus membranes and release the drug payload in a sustained release manner. Current study is focused on preparation several kinds of chitosan formul...
the present work focuses on preparation and characterization of erythromycin loaded gelatin nanoparticles through nanoprecipitation method. the procedure consists of the increase of the aqueous gelatin solution to the non-solvent phase containing lutherol f127. three different measures of cross-linker and polymer concentration were also examined, and the optimum concentration was found. the mor...
