I design for that condition, biopolymers. It's the future.

I said, You get into biopolymers. They looked straight through me.

Another graduate student showed that the polymers were safe.

In polymer chemistry, a structural unit is a building block of a polymer chain.

Description Synthetic fibers are made from synthesized polymers or small molecules.

This application is mainly used to modify the surface chemistry of polymers.

Natural polymers, well ... I think that's what's most important, because these polymers have been tried and tested in our ecosystem for the last billion years, in everything from mushrooms to crustaceans.

The polymers in mattress stuffing are used in breast implants.

When that moves into polymers, you can change the elasticity, the fluidity of the form.

As a proof of principle, we decided to synthesize a new family of biodegradable polymers, called polyanhydrides, for medical use.

We returned the proposal for another review it came back with the comment that the polymers were fragile and would break.

Yet one of my graduate students synthesized the polymers for his doctoral thesis.

Because of their broad range of properties, both synthetic and natural polymers play an essential and ubiquitous role in everyday life.

Carbon fiber reinforced polymer, carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic (CFRP, CRP, CFRTP or often simply carbon fiber, or even carbon), is an extremely strong and light fiber reinforced polymer which contains carbon fibers.

Biopolymers, these new ideas for materials, will come into play in probably a decade.

In our first grant proposal, in 1981, the reviewers said that we would never be able to synthesize the polymers.

Working in a hospital, I saw that almost all polymers used in medicine were derived from household objects.

The main structural components of plant cuticles are the unique polymers cutin and or cutan, impregnated with wax.

We then synthesized these polymers and discovered that by changing their composition, we could make them last in the body for a period ranging from days to years.

The first step was to select monomers a polymer s building blocks that would be safe in the human body.

We sent the proposal back for another review, only to be told that the grant should still not be funded, because the polymers would react with whatever drug we wanted to deliver.

However, after two years of work, I discovered that I could modify certain types of polymers to release molecules of virtually any size over a 100 day period.

In the future they will look like that, because we need to move away from those type of polymers and use that for medical equipment and more important things, perhaps, in life.

Meanwhile, our gatherer ancestors ate carbohydrates (polymers of glucose), which was also transported to the liver, via the glycolytic pathway, and broken down for energy.

The revised proposal was sent again for evaluation, and now the reviewers reason for rejecting it was that new polymers would not be safe to test on animals or people.

With Henry Brem, now the chief of neurosurgery at Johns Hopkins Hospital, we thought we could use these polymers to deliver drugs locally in the treatment of brain cancer.

So instead of using carbon from oil for synthetic processes, we have the chance of using carbon and capturing it back from the atmosphere, converting that into biopolymers or other products.

The comparison of linear polymers proteins made up of chains of amino acids, or DNA made up of chains of nucleotides held out the promise of a simple tabular approach to evolution.

Something similar happened when Jay Vacanti, a surgeon at Massachusetts General Hospital, and I had an idea in the 1980 s to combine three dimensional synthetic polymer scaffolds with cells to create new tissues and organs.

The exact process is still not understood theoretically in detail but its known from experiments that low molar mass systems tend to fill the pores completely, whereas polymers of sufficient chain length just cover the walls.

Moreover, the FDA s approval of polymer based local chemotherapy created a new paradigm in the drug delivery field, helping to pave the way for drug eluting stents and other local delivery systems.
