Since its invention 100 years ago, plastic , the superstar of the technological age, has become ugly and ungreen . But that’s about to change. An exhibition at London’s Science Museum this week could put it back on the cutting edge of science.
Have you ever hesitated in donating blood? The invention of “plastic blood” might make you feel better.
British scientists are working on the artificial blood as a replacement for real blood in emergency situations. It is made of plastic molecules(分子 ) and can join oxygen and transport it around the body. As a red, honey-like glue , plastic blood can be carried around conveniently . You just add water to make as much blood as you need.
The cells  of our body are strict about what molecules the let in and out . For example , if we inject protein or DNA  directly into the body, our immune ( 免疫 ) SYSTEM WILL DESTROY IT BEFORE IT REACHES THE CELLS.
To get around this , a British scientist has created drug-carrying plastic balls that fool the body into thinking they are natural. Once inside the cell, their contents are spread out through a small controlled explosion.
Skin transplants  are widely done these days. But removing a piece of skin from, say , the bottom to plant it on the face  can hurt and be troublesome.
The British company, Celltran, is working on plastic skin. Using plastic, they plan to take a small piece of the patient’s skin and grow it into an extra lay of skin on top of the plastic. a
The plastic  feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection .
