FUTURE TREATMENTS
Nanodevicescan make gene sequencing more efficient. Itwill revolut ionize the specificity of diagnostics andtherapeutics,
No operations, No more pills and chemotherapies,
Just one quick injection,
The nano sized machine communicate and target millions ofdifferent foreign bodies/ matters that may have developed inthe body,
It will search and destroy foreign objects, and rebuild thebodies vital cells.

Nanotechnology has been a boon for the
medical field by delivering drugs to specificcells using nanoparticles. The overall drugconsumption and side-effects can belowered significantly by depositing the activeagent in the morbid region only and in nohigher dose than needed. This highlyselective approach reduces costs and humansuffering.

FUTURE CANCER TREATMENTS
Nano moleculeswill travel and kill the cancer
Cancer cells can be killed by Magforce nonotheroperies, Nano xray therapies eliminatingpainful side effects of chemotherapy;loosinghair, hearing, etc..
Destroying tumor without killinghealthy cells
No addition of toxicsto body
