摘要
|
Self-propelled colloidal motors have great potential in the biomedical field such as active target delivery, detoxification, minimally invasive diagnostics, and nanosurgery, owing to their tiny size, autonomous motion, and navigation capacities. To enter the clinic, biomedical colloidal motors request the biodegradability of their manufacturing materials, the biocompatibility of chemical fuels or externally-physical fields, the capability of overcoming various biological barriers. I will first introduce the recent advances of synthetic colloidal motors based on controlled chemical self-assembly and how such a strategy permits the realization of synthetic motors with the engineering features, such as sizes, shapes, composition, self-propulsion, collective motion and other functions. Next, I will talk how these chemically assembled motors could be designed to overcome the mentioned biological barriers. The challenges and future research priorities will be also addressed.
