Nanopaticles one hundred times smaller than a human blood cell are being used to help direct healthy cells to damaged areas in blood vessels. The nanoparticles are made of biodegradable polyactic acid and coated with iron oxide. By inducing an external magnetic field, the particles are directed to steel stents located in damaged vessels. Researchers at the Philidelphia Childrens Hospital say that this method of targeting cells to areas of damage could have wide ranging implications, from directing cells to recoat stents and prevent vessel blockage in cardiovascular patients, to introducing stem cells to pins in bones or medication to other areas where stents are used such as the oesophagus and bile duct.

Modelling nano devices seem to be the point to think up.Mimicing spermhit is in.same way i think one can imagine midsize things like spects,hearingaids,collapse the idea to tiny implants placed suitably in brain to do the job far better.Monitoring cerebral action is good for type6 behaviours.
