Transmembrane Serine Protease

Matriptase is a type II transmembrane serine protease highly expressed on the surface of tumor cells and participated in a range of human cancers including those of the breast, cervix, ovaries, prostate, colon and gastrointestinal tract. In this study, we developed a new matriptase detection probe with gold nanoparticles (AuNPs). A fluorescence dye was attached to AuNP surface through the bridge of peptide substrate (GRQSRAC). The fluorescence was quenched due to the fluorescence resonance energy transfer (FRET) between AuNP and the fluorescence dye. The fluorescence recovery properties were confirmed by dithiothreitol in vitro. The result of in vitro cell research indicates that the gold nanoparticle probe is sensitive and specificitive for the detection of matriptase expression in early tumor and has great potential in biomedical application.

Effective Use

In material science, green method for synthesis of nanomaterials is feasible, cheaper and eco-friendly protocol. To accomplish this phenomenon, present study was aimed to synthesize Copper oxide nanoparticles using leaf extract of Aloevera with two different precursors CuCl2.2H2O (Cupric chloride) and CuSo4.5H2O (Cupric sulfate). The extraction of Aloevera is employed as reducing and stabilizing agent for this synthesis.Copper oxide Nanoparticles is effective use of biomedical application due to their antibacterial function. The synthesized Copper oxide nanoparticles were characterized by X-Ray Diffraction Spectroscopy (XRD), Energy Dispersive Spectroscopy (EDX), FourierTransform Infrared Spectroscopy (FT- IR) and Scanning Electron Microscope(SEM). XRD studies reveal the crystallographic nature of Copper oxide nanoparticles. Furthermore the Copper oxide nanoparticles have good Antibacterial activity against both gram negative (E.Coli, Klebsiella pneumonia) and gram positive (Bacillus cereus, Staphylococcus aureus)bacteria.
