Abstract
Inefficient tumor penetration caused by the characteristics of tumor microenvironments is a primary obstacle to improving drug delivery efficiency, which restricts the chemotherapy drug efficacy. One such promising idea is to construct micro/nanomotors (MNMs) as an effective delivery vehicle by way of producing autonomous motion and converting exogenous stimuli or external energies from the surrounding environment into mechanical forces. In this research, the Pt/DOX nanomotor was prepared, and the enhanced diffusion and positive chemotaxis driven by substrates were verified in vitro, proof of the enhanced cellular uptake and deep penetration of Pt/DOX. As a novel nanovehicle, Pt/DOX potentially provides an intriguing approach to foster the tumor-deep penetration and enhance the drug delivery efficiency.
