23 Jul Temperature-responsible photothermal nanomaterial and preparation method thereof
Abstract
The invention discloses a temperature-responsible photothermal nanomaterial and a preparation method thereof. A nanomaterial polydopamine (PDA-NPs) used as a substrate is copolymerized with 3-[N,N-dimethyl-[2-(2-methylpropyl-2-enoyloxy)ethyl]azaniumyl]propane-1-sulfonate (SBMA) by using 2-(dimethylamino)ethyl methacrylate (DMAEMA) to adjust the upper critical solution temperature (UCST), and chemical cross-linking is carried out to form a gel. The temperature-responsible photothermal nanomaterial prepared in the invention has a sensitive response performance to the ambient temperature, has a good photothermal effect, good self-healing ability and good cell/tissue adhesion, and can be applied to fields of controlled drug delivery, sensors and tissue engineering.
