Abstract Purpose: our goal is to reduce the release rate of methotrexate (MTX) and increase cell death efficiency. Methods: Carboxylated multi-walled carbon nanotubes (MWCNT-COOH) were functionalized with MTX as a cytotoxic agent, FA as a targeting moiety and polyethylene amine (PEI) as a hydrophilic agent. Ultimately, MWCNT-MTX and MWCNT-MTX-PEI-FA were synthesized. Methotrexate re...

Objective. The objective of the present study is to synthesize and optimize bovine serum albumin nanoparticles coated with ofloxacin drug nano conjugate and evaluation of control release and anti bacterial activity against clinical isolate of Pseudomonas aeruginosa,Methods.Simple coacervation technique was implemented for preparation of BSA nanoparticles and optimization was carried out with va...

Localized delivery of nucleic acids to target sites (e.g., diseased tissue) is critical for safe and efficacious gene therapy. An ultrasound-based technique termed acoustic droplet vaporization (ADV) has been used to spatiotemporally control the release of therapeutic small molecules and proteins contained within sonosensitive emulsions. Here, ADV is used to control the release of lipoplex-cont...

BACKGROUND AND AIMS Recent studies have shown that low molecular weight heparins are effective in the treatment of inflammatory bowel disease. Therefore, there is considerable interest in the development of an oral colonic delivery pharmaceutical system allowing targeted release of heparin in the inflamed tissue. The objective of this study was to prepare microparticles for the oral administrat...

The goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. Rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. The mesoporous silica nanoparticles were prepared by using Tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); The prepared nanoparti...

Human serum albumin nanoparticles (HSA-NPs) were synthesized using the modified desolvation method. Fourier transform infrared spectroscopy (FT-IR), electronic absorption spectroscopy (UV-Vis), Zeta Sizer as well as field emission scanning electron microscope (FE-SEM) of the sample confirmed the formation of HSA NPs with an average size of 68 nm. The obtained results shown that HSA-NPs was succ...

The aim of the current study was to formulate and optimize the formulation on the basis of in vitro performance of microsphere. A 3(2) full factorial design was employed to study the effect of independent variables, polymer-to-drug ratio (X(1)) and stirring speed (X(2)), on dependent variables, encapsulation efficiency, particle size, and time to 80% drug release. The best batch exhibited a hig...
