  一种光敏性聚乙二醇基抗菌水凝胶敷料及其 制备方法

  摘要：

  本发明涉及一种光敏性聚乙二醇基抗菌水凝胶敷料及其制备方法，该敷料是在聚乙二醇水凝胶基体上共价接枝有抗生素。其制备方法包括：将小分子抗生素通过紫外光可断裂分子修饰到末端带双键的聚乙二醇大分子链，得到紫外光可断裂的聚乙二醇基大分子，与未修饰的含末端双键的聚乙二醇分子共混作为单体，在交联剂、引发剂作用下通过热引发双键交联制备得到具有光敏性抗菌性能的水凝胶敷料。本发明的原料具有良好的生物形容性，得到的水凝胶敷料具有一定的力学性能和吸水溶胀性能，且在365nm波长的紫外光照射下能够实现抗生素的有效控制释放，具备良好的紫外光响应性抗菌性能，适用于创面的保护和感染治疗。

  In various embodiments methods are provided for identifying and/or quantifying one or more antigens of interest (biomarkers) on the surface of cell- or tissue-specific exosomes. In an illustrative embodiments the methods comprise: i) incubating a population of exosomes with one or more tissue-specific antibodies that bind an antigen specific to a tissue or cell type of interest that produces exosomes, where the tissue specific antibodies are attached to acceptor bead or magnetic beads so the antibodies bind exosomes displaying the antigen; ii) obtaining a purified population of exosomes bound by the tissue specific antibodies with and/or without photocleavable linker based technology; iii) incubating a test subset of the isolated tissue-specific exosomes with acceptor beads attached to test antibodies that bind an antigen of interest thereby binding exosomes that display the antigen of interest and a control subset with negative control acceptor beads; v) incubating the test subset of isolated exosomes and the control subset of exosomes with a donor-bearing antibody that binds an exosome specific antigen; and vi) detecting a signal produced upon illumination of the control subset and/or the test; and vii) detecting the antigen(s) of interest.

  we decided to develop a method for the preparation of vitamin B12 conjugates that release tethered molecules upon exposure to light. Herein, we report vitamin B12 derivatives possessing a photolabile linker suitable for conjugation with amines, azides, and alkynes. The potential applications of such conjugates are broad and include the delivery of drugs, labels, and imaging agents to their place of
