incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

abstractvarious nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (slns). due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. different strategies have been employed to overcome this problem. in this direction, the present study introduces erodible in-situ forming gel systems ...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...
