A new strategy for in situ preparation of highly fluorescent CdTe quantum dots (QDs) with 3-mercaptopropionic acid (MPA) and hyperbranched poly(amidoamine)s (HPAMAM) as co-stabilizers was proposed in this paper. MPA and HPAMAM were added in turn to coordinate Cd2+. After adding NaHTe and further microwave irradiation, fluorescent CdTe QDs stabilized by MPA and HPAMAM were obtained. Such a strat...

graphene, after its first production in 2004 have received lots of attentions from researchers because of its unique properties. high mobility, high sensitivity, high selectivity and high surface area make graphene excellent choice for bio application. one of promising graphene base device that has amazingly high sensitivity is graphene field-effect transistor (gfet). this review selectively su...

Abstract The sensing of bioactive molecules based on photochemical techniques has become one the fastest-growing scientific fields. Surface-enhanced Raman scattering (SERS) is a highly sensitive technique for detection low-concentration molecules, including DNA, microRNA, proteins, blood, and bacteria; single-cell identification; bioimaging; disease diagnosis, providing abundant structural info...

This review focuses on the recent development and various strategies in the preparation, microstructure, and magnetic properties of bare and surface functionalized iron oxide nanoparticles (IONPs); their corresponding biological application was also discussed. In order to implement the practical in vivo or in vitro applications, the IONPs must have combined properties of high magnetic saturatio...

Copper sulphides, as a novel kind of photothermal agent for photothermal therapy (PTT) of cancer cells, have attracted increasing attention in recent years due to good photostability, synthetic simplicity, low toxicity and low cost. However, the unsatisfactory photothermal conversion efficiency of copper sulphides limits their bioapplication as PTT agents. Herein, Cu7.2S4 NCs with a mean size o...

RF sputtering was achieved to get Ca3Ce(PO4)3 phase from target of 60wt%CeO2/TCP on stainless steel 316L surface for bioapplication. The selection ceria and tricalcium phosphate is according fact the importance these materials in biomedical media. produced confirmed by XRD analysis (JCPDS card No. 09-0169) with important 2θ values at (≈ 28.4, 33.7, 46.6 44.7). FESEM/EDS exam showed smoother ind...
