Effect of silk sericin on morphology and structure of calcium carbonate crystal

Frontiers of Materials Science 2013年第2期7卷 177-183页

作者： Rui-Bo ZHAO Hua-Feng HAN Shao DING Ze-Hao LI Xiang-Dong KONG Xinyuan Institute of Medicine and Biotechnology College of Life Sciences Zhejiang Sci-Tech University Hangzhou 310018 China College of Materials and Textile Zhejiang Sci-Tech University Hangzhou 310018 China

In this paper, silk sericin was employed to regulate the mineralization of calcium carbonate （CaC03）. CaCO3 composite particles were prepared by the precipita- tion reaction of sodium carbonate with calcium chloride solution in the presence of silk sericin. The as-prepared samples were collected at different reaction time to study the crystallization process of CaCO3 by scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy （FTIR）, thermogravimetric analysis （TGA） and X-ray diffraction （XRD）. The results showed that silk sericin significantly affected the morphology and crystallographic polymorph of CaCO3. With increasing the reaction time, the crystal phase of CaCO3 transferred from calcite dominated to vaterite dominated mixtures, while the morphology of CaCO3 changed from disk-like calcite crystal to spherical vaterite crystal. These studies showed the potential of silk sericin used as a template molecule to control the growth of inorganic crystal.

Temperature-pH Sensitive IPN Hydrogels Composed of silk sericin and Poly(N-isopropylacrylamide)

引用

Chinese Chemical Letters 2006年第3期17卷 403-406页

作者： Wen WU Wen Jing LI Li Qun WANG Ke Hua TU Wei Lin SUN Deparment of Polymer Science and Engineering Zhejiang University Hangzhou 310027 Ningbo Institute of Technology Zhejiang University Ningbo 315100

Interpenetrating polymer network （IPN） composed of silk sericin （SS） and poly（N-isopropylacrylamide）（PNIPAAm） was prepared. The morphology of the IPNs, in which the SS phase was stained with ammonium cuprate, was examined with TEM and a relative homogeneous distribution of the two polymers was exhibited. The swelling behavior of the IPN hydrogels showed both temperature and pH dependences.

The use of silk sericin protein as a biomaterial to co-encapsulate probiotic Lactobacillus casei TISTR 1463 with alginate and various prebiotics was *** addition,0.2%silk sericin was also evaluated as a coating material to improve the viability of probiotic *** sericin coating has the potential to enhance probiotic survival in freeze-dried *** refrigerated storage condition of 4℃for 120 days,alginate-silk sericin-maltitol with silk sericin coating(ASM-C)provided the best performance with the lowest inactivation rate(k)and the highestδparameter(the first decimal reduction time)applied by the log-linear and Weibull models,***,the stability was relatively low at the temperature of 30℃.Co-encapsulation of alginate-silk sericin-prebiotic and coated with silk sericin exerted a protective impact on the strain survival when exposed to high temperatures and transited through the digestive system.
