Bifunctional linkers for modification of TiO2 nanoparticles were prepared containing a catechol group for TiO2 surface attachment and a maleimide and alkyne group for Michael addition and Cu catalysed Huisgen cycloaddition respectively. Peptide and fluorophore functionalised TiO2 NPs were prepared, different purification methodologies were explored and conjugates were characterized using a range of methods.
制备了用于修饰二氧化钛纳米粒子的双功能连接体,其中含有用于二氧化钛表面附着的邻苯二酚基团,以及分别用于迈克尔加成和铜催化惠斯根环加成的马来酰亚胺基团和炔烃基团。制备了肽和荧光团功能化的 TiO2 NPs,探索了不同的纯化方法,并使用一系列方法对共轭物进行了表征。
