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...

Gene delivery holds promise to cure many inheritable or acquired diseases that are currently considered incurable. Liposomes are clinically well-established drug-delivery vehicles with promising properties, including biocompatibility, high drug-to-carrier ratios, and straightforward drug-encapsulation capability. However, widespread clinical use of this delivery system still requires better del...

In this work, an simple and fast method based solid phase extraction for preconcentration and separation of trace amount of Fe(III) ions from water samples prior to its determination by flame atomic absorption spectrometry (FAAS) was developed. The silver nanoparticles coated silica gel was modified by morin and then it was used as a adsorbent. The silver nanoparticle coated silica gel was prep...

Magnetite nanoparticles of Fe(3)O(4) have been found to grow into large highly branched nanostructures including nanochains and highly branched nanotrees in the solid state through a postannealing process. By varying the preparation conditions such as annealing time and temperature, the nanostructures could be easily manipulated. Changing the starting concentration of the magnetic nanoparticle ...
