The fluorescence spectra and binding reaction of neutral red with nucleic acids have been studied. At pH=4.5, a new method for the determination of trace nucleic acids based on fluorescence quenching measurement was e...
Distinct spectral differences among Saccharomyces cerevisiae, Corynebacterium glutamicum, Escherichia coli, Staphylococcus aureus were observed from their high quality infrared spectra in the frequence regions 900-1 8...
A procedure for the preparation of continuous rod consisting of poly(glycidyl methacrylate\|co\|ethylene dimethacrylate) for immobilized metal affinity chromatography (IMAC) is presented. When chelating Cu(Ⅱ), Zn(Ⅱ)...
In this paper, a novel protein templating approach to synthesize macroporous materials has been demonstrated. Sponge like architectured macroporous oxides(silica, titania) have been firstly synthesized by using low co...
A novel pulsed-electrospray device is reported in this paper. With such an apparatus, the observation of the electrospray process under the pulsed high voltage conditions has been successfully made with microscope, os...
