This work is aimed at preparation of small silver nanoparticles (Ag NPs) with various sizes using two-step preparation method. The silver bromide nanoparticles were prepared in the first step and they were reduced to metal silver nanoparticles in the second step. Size of prepared silver nanoparticles was controlled by using of several modifiers. Two surfactants (SDS and Tween 80) and two natura...

In this study, optimized freeze-dried finasteride nanoparticles (NPs) were prepared from drug nanosuspension formulation that was developed using the bottom-up technique. The effects of four formulation and processing variables that affect the particle size and solubility enhancement of the NPs were explored using the response surface optimization design. The optimized formulation was morpholog...

Triple-negative breast cancer (TNBC) is one of the most invasively malignant human cancers and its incidence increases year by year. Effective therapeutics against them needs to be developed urgently. In this study, a kind of angiopep-2 modified and intelligently particle size-reducible NPs, Angio-DOX-DGL-GNP, was designed for accomplishing both high accumulation and deep penetration within tum...

Curcumin (CUR), a yellow polyphenol compound is reportedly associated with a diverse therapeutic potential. Despite all curative properties of CUR, its usage in oral administration is restricted due to low bioavailability, low aqueous solubility and poor absorption rate. The aim of this study was to develop a nontoxic nanocurcumin (CUR-NPs) with enhanced bioavailability. For this reason, the CU...

Neovascularization (NV) of the cornea can disrupt visual function, causing ocular diseases, including blindness. Therefore, treatment of corneal NV has a high public health impact. Epigalloccatechin-3-gallate (EGCG), presenting antiangiogenesis effects, was chosen as an inhibitor to treat human vascular endothelial cells for corneal NV treatment. An arginine-glycine-aspartic acid (RGD) peptide-...

Objective(s): The present study aimed to prepare polycaprolactone (PCL) scaffolds with high porosity and pore interconnectivity, in order to copy the microstructure of natural bones using the thermally induced phase separation (TIPS) technique. Materials and Methods: The scaffolds were coated with chitosan (CH), bioactive glass (BG), and gelatin nanoparticles (GEL NPs) and assessed using ...

We report an innovative low-cost wet precipitation synthesis method for gelatin-modified zinc oxide nanoparticles (GM ZnO NPs) at the interface between gelatin hydrogel and aqueous electrolyte. Diffusion of ammonia through matrices with different contents induced product in contact surface solution ions. The obtained precipitate was subjected to thermal treatment partially decompose adsorbed NP...

Silver nanoparticles (Ag NPs) are an effective antibacterial agent, but their application in food packaging is limited due to easy agglomeration and oxidation. In this study, microcapsules were fabricated using Ginkgo biloba essential oil (GBEO) as core material chitosan type B gelatin biopolymer capsule materials. These then modified with green-synthesized Ag NPs, blended into the polylactic a...

Gold nanoparticles (Au NPs) were prepared by direct current atmospheric pressure glow microdischarge (dc-μAPGD) generated between a miniature argon flow microjet and a flowing liquid cathode. The applied discharge system was operated in a continuous flow liquid mode. The influence of various stabilizers added to the solution of the liquid cathode, i.e., gelatin (GEL), polyvinylpyrrolidone (PVP)...
