Nanomotors can swim past non-cancerous cells but adhere to the charged cancer secreted matrix in a tumor model. This can be used to localise a swarm of nanomotors near cancerous...

A variety of nanoparticles are designed for targeted drug delivery, but unfortunately only a very small proportion of the injected nanoparticles reach the target site such as solid tumors. The...
