Study Results from Pingdingshan University Broaden Understanding of Globins

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Proteins are discussed in a new report. According to news originating from Pingdingshan, People's Republic of China, by NewsRx correspondents, research stated, "A simple, convenient, and controllable strategy was reported in this contribution for protein-assisted synthesis BHb-conjugated PbS nanocubes. Powder X-ray diffraction, energy disperse X-ray spectroscopy, transmission electron microscopy, high-resolution transmission electron microscopy, and selected-area electron diffraction characterizations were used to determine the structure and morphology of BHb-conjugated PbS nanocubes."

Our news journalists obtained a quote from the research from Pingdingshan University, "The prepared PbS nanocrystals with cubic rock salt structure were uniform and monodispersed with homogeneous size around 12 nm. The results of Fourier transform infrared and circular dichroism assay proved that Pb2+/PbS had coordination interaction with functional groups of BHb besides physical-binding effect, and the secondary structure of protein significantly changed with this interaction. Thermogravimetric analysis results confirmed the existence of BHb in PbS nanocrystals and indicated that the conjugate bonds existed between PbS and BHb."

According to the news editors, the research concluded: "A clear perspective was shown here that special nanostructure could be created by using proteins as a mediating template at the inorganic-organic interface."
