Studying the dynamic mechanism of transporting a single drug carrier-polyamidoamine dendrimer through cell membranes by force tracing.

Although drug delivery based on nanomaterials has shown great potential in practical applications, the trans-membrane mechanism of the drug carrier is still unclear due to technical limitations. Here, we report the dynamic transporting process of a single dendritic polyamidoamine particle via cell membranes in real time by the force tracing technique.
