Ti prosthesis have shown better biological compatibility, mechanical performance, and resistance to corrosion in cases of bone replacements. Nevertheless, fully dense connection with bone-host tissues show stress-shielding phenomenon that, together the development frequent undesirable microbial infections, may lead implant failures. To overcome these issues, present study aimed at a novel combi...
We investigated hydroxyalkylphosphonate monolayers as a novel platform for the biofunctionalization of silicon-based field effect sensor devices. This included a detailed study of the thin film properties of organophosphonate films on Si substrates using several surface analysis techniques, including AFM, ellipsometry, contact angle, X-ray photoelectron spectroscopy (XPS), X-ray reflectivity, a...
One of the backbones in nanomedicine is to deliver drugs specifically to unhealthy cells. Drug nanocarriers can cross physiological barriers and access different tissues, which after proper surface biofunctionalization can enhance cell specificity for cancer therapy. Recent developments have highlighted the potential of mesoporous silica (PSiO(2)) and silicon (PSi) nanoparticles for targeted dr...
Upconversion nanocrystals NCs of NaYF4:Yb,Ln Ln=Er and Tm in cubic and hexagonal phases were synthesized in oleic acid OA and/or trioctylphosphine TOP with octadecene ODE via a thermolysis method. Only cubic-phase NCs were obtained in OA/ODE and TOP/ODE solvents; on the other hand, the hexagonal-phase NCs resulted in OA/TOP/ODE. The phase transition from cubic to hexagonal was induced by a liga...
