Colloidal HSA - Graphene oxide nanosheets for sustained release of oxaliplatin: Preparation, release mechanism, cytotoxicity and electrochemical approaches.

A novel sustained release carrier of graphene oxide nanosheets functionalized by human serum albumin nanoparticles (FGO-NSs) was synthesized and characterized by field emission scanning electron microscopy (FESEM), zeta sizer analysis, absorption spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR) studies. The cell viability of GO-NSs, HSA-NPs and FGO-NSs has been tested against human foreskin fibroblast normal cell line, HFFF2 by MTT assay technique. Loading efficiency and release properties of oxaliplatin (OX), as an effective chemotherapeutic agent in the treatment of cancers, from HSA-NPs and FGO-NSs were studied.

Effect of nanocomposite packaging containing ZnO on growth of Bacillus subtilis and Enterobacter aerogenes.

Recent advances in nanotechnology have opened new windows in active food packaging. Nano-sized ZnO is an inexpensive material with potential antimicrobial properties. The aim of the present study is to evaluate the antibacterial effect of low density Polyethylene (LDPE) containing ZnO nanoparticles on Bacillus subtilis and Enterobacter aerogenes.
