Synthesis and physicochemical characterization of photo crosslinked hydrogels of alginate/gelatin and a-tocopherol nanocapsules for their potential use as biomaterials por Palacios Santos, José Ernesto

“…Based on what previously explained the question was raised: Will hydrogels made with biopolymers and loaded with nanoencapsulated a-tocopherol promotes a faster and more effective cell proliferation response? During this investigation, the synthesis of the hydrogels was made by photo crosslink and their physicochemical characteristics were analyzed by gravimetric, spectrophotometric and rheological techniques, while the nanocapsules were formed using nanoprecipitation method and their physicochemical characteristics were also analyzed. …”

Bio-Fabrication and Experimental Validation of an Mg - 25Ca - 5Zn Alloy Proposed for a Porous Metallic Scaffold por Campos Becerra, Luis Humberto, Torres Castro, Alejandro

“…Considera-tions on the preparation of an alloy of Mg - 25 wt% Ca - 5 wt% Zn and its morphological charac-terization will help researchers understand its applicability for the development of new surgical techniques and lead to a deeper investigation of alternative treatments. However, it is very im-portant to bear in mind the mechanical effect of elements such as Ca and Zn on the degradation of the alloy matrix; the best alternative to predict the biological-mechanical potential starts with the selection of the essential-nutritional elements and their mechanical evaluation by mi-cro-indentation due to the fragility of the matrix. …”
