Bio-MOF-29 crystallized in orthorhombic crystal system with P212121 space group. In vitro adsorption studies of four different drugs, terazosine hydrochloride, telmisartan, glimpiride and rosuvastatin have been carried out for Bio-MOF-29. Drugs adsorption estimations of drugs loaded Bio-MOF-29 have been carried out through High Performance Liquid Chromatography (HPLC), which reveals that these drugs are successfuly adsorbed in it. Also the slow release of adsorbed drugs after intervals was observed through HPLC. Thermograms and powder XRD patterns of Bio-MOF-29 before and after drugs adsorption were also recorded to elaborate the phenomenon of drugs adsorption in Bio-MOF-29.展开更多

Nano sized morphology of all these materials have been obtained by scanning electron microscopic technique. Mass spectrometric studies of all these materials have been conducted for determination of their molar masses. All these nanobioMOFs have been found to exhibit photocatalytic hydrogen generation in pure water upon irradiation at wavelengths longer than 650 nm. The amounts of quantum yield of hydrogen generation at 650 nm in water was 4.5%, 4.0% and 3.5% for cobalt argeninate, cobalt asparaginate and cobalt glutaminate respectively. The apparently higher yield of hydrogen generation from these amine functionalized nanobioMOFs can direct to the development of more nano sized functionalized MOFs for water splitting.展开更多
