Transiently protect Tighten the skin and remove

wrinkles Transfer drugs to diagnose skin

related diseases like eczema and dermatitis

Silicon-based polymer It could be applied to the skin as

thin and fine coating as a gel or cream

It has the ability to prevent water loss from the dry skin.

Cosmetic and non-cosmetic applications

No side effects High performance Burns

PROS

Replace diseased or damaged organs

Meet the huge demand of healthy donor organs

Organ rejection can be solved due to artificial organs

Time taken to create or grow an artificial organ is lesser than waiting period for finding a suitable donor

CONS

Possible presence of the disease in the base tissue which is used to create the organ

Cost High chances of organ

failure Ethical issues
