    • An Inkjet printing method, system, and computer-usable tangible storage device to print cells and biomaterials for three-dimensional cellular scaffolds and engineered skin grafts are disclosed. The process simultaneously deposits living cells, nutrients, growth factors, therapeutic drugs along with biomaterial scaffolds at the right time and location. This technology can also be used for the microvasculature fabrication using appropriate human microvascular endothelial cells and fibrin to form the microvasculature. When printing human microvascular endothelial cells in conjunction with the fibrin, the cells aligned themselves inside the channels and proliferated to form confluent linings. The 3D tubular structure was also found in the printed patterns. Simultaneously printing biological materials to form a three-dimensional cellular scaffold promotes human microvascular endothelial cell proliferation and microvasculature formation.

    • Macromolecular imprinted silica particles ("MIP") in the presence of polymer grafted carbon black are disclosed. The disclosed molecular imprinted beads can detect disease in body fluids. For the silica gel matrix, tetraethyl orthosilicate (TEOS) was used as the backbone monomer and 3-aminopropy/triethoxysilane (APS) as a functional monomer. Carbon black was added to the sol-gel process, yielding black silica particles. Furthermore, sodium dodecyl sulfate (SDS) was used as a structure-directing agent to increase network diffusion of the template. A total of 16 M!Ps were synthetized in parallel with variables that evaluate the role of key reactants in the synthesis procedure. Agglomeration tests were performed with ail 16 M!Ps in the presence of their template, alongside their respective controls using only phosphate buffered saline ("PBS"). Each of the MIPs was evaluated using a novel device capable of simultaneously measuring up to four samples for near infrared transmission.
    • 公开了在聚合物接枝炭黑存在下的大分子印迹二氧化硅颗粒(“MIP”)。 所公开的分子印迹珠可以检测体液中的疾病。 对于硅胶基质,使用原硅酸四乙酯(TEOS)作为主链单体和3-氨基丙基/三乙氧基硅烷(APS)作为官能单体。 将炭黑加入到溶胶 - 凝胶法中,得到黑色二氧化硅颗粒。 此外,使用十二烷基硫酸钠(SDS)作为结构导向剂以增加模板的网络扩散。 共计16 M!Ps与评估关键反应物在合成过程中的作用的变量并行合成。 在其模板存在的情况下,使用只有磷酸盐缓冲盐水(“PBS”)的各自的对照进行聚集测试。 使用能够同时测量多达四个用于近红外透射的样品的新型装置来评估每个MIP。
