    • A method of forming a cross-linked protein structures includes preparing a solution of protein dissolved in a benign solvent and forming an intermediate protein structure from the solution. The intermediate protein structure can be cross-linked by providing for a specific ratio of chemical cross-linking agents to form the cross-linked protein structure. The solution can be prepared by adding a cross-linker of N-hydroxysuccinimide (NHS) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) at a ratio of two-to-one of NHS to EDC to alcohol. PBS buffer (20X) can be added to the solution until the volume ratio of PBS buffer (20X) to alcohol is about one-to-one. About 16 percent by weight of protein can be dissolved in the solution. The solution can be electrospun to form an intermediate protein structure. After a period of time, the protein structure can be cross-linked to form the cross-linked protein structure.
    • 形成交联蛋白质结构的方法包括制备溶解在良溶剂中的蛋白质溶液并从溶液形成中间体蛋白质结构。 通过提供特定比例的化学交联剂以形成交联的蛋白质结构,可以交联中间体蛋白质结构。 该溶液可以通过以NHS与EDC的二对比与乙醇的比例加入N-羟基琥珀酰亚胺(NHS)和1-乙基-3-(3-二甲基氨基丙基)碳二亚胺盐酸盐(EDC)的交联剂来制备 。 可以将PBS缓冲液(20X)加入到溶液中,直到PBS缓冲液(20X)与醇的体积比约为1比1。 约16重量%的蛋白质可以溶解在溶液中。 该溶液可以静电纺丝以形成中间体蛋白质结构。 一段时间后,蛋白质结构可以交联形成交联的蛋白质结构。

    • Small particles of polymeric material are produced by expansion of a mixture of monomers and a propellant. The size and shape of the particles can be precisely tailored by materials selection and expansion conditions. Particles of 10 nanometers to 100 microns can be produced. If monomers exhibiting solid state reactivity are utilized, the particles thus formed can be polymerized at any time after formation. The particles produced by this method can be molecularly imprinted by incorporating a template into the particle prior to fully curing the particle, in a manner which allows selective extraction of the template from the cured particle after formation without deformation of the imprint site. A two step polymerization process allows the particles to be deposited on and adhered to a wide variety of substrates without additional agents. The molecularly imprinted particles can be used in a wide variety of applications including the selective binding of analyte from a sample, where the analyte is the same as the template or is of substantially the same size and has a similar arrangement of chemical functional groups. Imprinted molecularly imprinted particles can be used for targeted delivery of agents in biological applications. Non-imprinted particles formed by the expansion technique using monomers of solid state reactivity can be used in optical data storage systems.
    • 通过膨胀单体和推进剂的混合物来生产聚合物材料的小颗粒。 颗粒的尺寸和形状可以通过材料选择和膨胀条件精确地定制。 可以生产10纳米至100微米的颗粒。 如果使用表现出固态反应性的单体,则由此形成的颗粒可以在形成后的任何时间聚合。 通过该方法制备的颗粒可以通过在完全固化颗粒之前将模板并入颗粒中以可以在形成后从固化颗粒中选择性提取而不使压印位点变形的方式来分子印迹。 两步聚合方法允许颗粒沉积在各种基材上并粘附到多种基材上,而不需要额外的试剂。 分子印迹的颗粒可以用于各种应用,包括分析物与样品的选择性结合,其中分析物与模板相同或具有基本相同的尺寸并且具有类似的化学官能团排列。 印迹分子印迹颗粒可用于生物应用中的试剂的靶向递送。 通过使用固态反应性单体的膨胀技术形成的非印刷粒子可用于光学数据存储系统。
