标题:一系列氟醚甜菜碱两性表面活性剂的表面活性:氧的作用
摘要:由于 Pfos,Pfoa 及其衍生物因其潜在的生物蓄积性和毒性而被斯德哥尔摩公约禁止,人们试图用短链表面活性剂替代传统的含氟表面活性剂.尽管短链替代品可以减轻生物积累,但表面活性受到了损害.氟工业不断寻求有效的解决方案.在这项工作中,我们制备并研究了一系列氟醚甜菜碱表面活性剂的表面活性和铺展性能.讨论了氧对表面活性的作用.我们发现将氧原子插入氟化链可以增加疏水性,从而增强表面活性.根据经验,一个氧的贡献大约是二氟亚甲基的一半.而且,引入氧使结构多样化,以填补短氟表面活性剂和长氟表面活性剂之间表面活性的空白.总之,这项工作为分子设计提供了基础知识.

标 题:New method for automated on-demand biomolecular array synthesis
发明人：ZHANG YIXIN; LIN WEILIN
权利人:UNIV DRESDEN TECH
摘要:The invention provides an amphiphilic coating for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, comprising a hydrophilic chemical structure and a lipophilic group, wherein said peptides and small molecular compounds differ from spot to spot from each other in the chemical structure, characterized in that said amphiphilic coating possesses low wettability to polar aprotic solvents used in the array synthesis; said amphiphilic coating possessing low wettability is designed that it can be converted to a coating possessing high wettability by hydrolysis of the lipophilic group; and said amphiphilic coating comprises an amino group for the reaction with an electrophilic reagent. The invention further provides a solid support comprising said amphiphilic coating and a method for method for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, wherein said planar surface of a solid support comprises said amphiphilic coating. Said method includes the enhancing of the wettability of a glass surface to organic solvents to realize automated on-demand biomolecular array synthesis comprising both, peptides and small molecular compounds. The amphiphilic surface can be switched to a hydrophilic surface, resulting in high density arrays suitable for protein- and cell-based screening.
