Dr Chenjie XU and his research team recently developed a new generation of microneedles technology which allows the intradermal delivery of living cells in a minimally invasive manner. The new technology “crymicroneedles” are the icy microneedles that can deliver therapeutic cells into the skin layers. Their experiment showed that vaccination using therapeutic cells through this new technology elicited robust immune responses against tumours in mice, paving the way for developing an easy-to-use cell therapy and other therapeutics against cancers and other diseases. The mirconeedles would penetrate through the skin, detach from the patch base and then melt.

The latest findings have been published in Nature Biomedical Engineering, titled "Cryomicroneedles for Transdermal Cell Delivery".
