-PHA is generally produced by organisms in environments when carbon is plentiful but other nutrients are limiting.
-PHA is made by microorganisms and can easily be broken down by them
-PHA can be produced commercially by fermentation of microorganisms in the presence of an inexpensive carbon source.
-For use in medical applications, materials must be bio compatible, which means they cannot cause severe immune reactions when introduced to soft tissues or blood of a host organism.
-PHA materials must also not elicit immune responses during degradation in the body to be considered biocompatible. ]]> 2017-04-16 23:26:05 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166487567 nuraisyahsamad https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166488009 -An obvious medical application for the polymer is for scaffolding material in tissue engineering. ]]> 2017-04-16 23:41:06 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166488009 https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166491799 The Application of PHA

1. Packaging films (for food packages), bags, containers, paper coatings.
2. Biodegradable carrier for long-term dosage of drugs, medicines, insecticides, herbicides, insecticides or fertilizers.
3. Disposable items such as razors, utensils, diapers, feminine hygiene products, cosmetics containers, shampoo bottles, cups etc.
4. Starting material for chiral compounds.
5. Medical applications – Surgical pins, sutures, staples, swabs, wound dressings, bone replacements & plates and blood vessel replacements, Stimulation of bone growth by piezoelectric properties.

2. PHA is also an interesting class of biomaterials for the development of tissue-engineered cardiovascular products.
3. PHA can be used as stereoregular compounds which can serve as chiral precursors for the chemical synthesis of optically active compounds. ]]> 2017-04-17 01:40:34 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166493592 martiniwelsondion https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497367 2017-04-17 02:57:53 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497367 martiniwelsondion https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497388 2017-04-17 02:58:25 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497388 martiniwelsondion https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497410 2017-04-17 02:58:52 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497410 martiniwelsondion https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497434 2017-04-17 02:59:24 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497434 martiniwelsondion https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497534 PHAs are still far from joining the competitive level of production costs compared to petroleum-based polymers such as PP or PE. Hence, currently, PHAs can be only considered for advanced applications, in which they cannot be replaced by petroleum-based polymers. Correspondingly, PHAs are well-suited for any application that requires biocompatibility and/or biodegradability of the polymer. Notably, purity requirements are high for such applications, and the removal of impurities, such as endotoxins, further increases the production costs. For medical applications, in particular the homopolymers PHB and PHV as well as the statistical copolymer PHB-stat-PHV have been investigated.]]> 2017-04-17 03:01:27 UTC https://padlet.com/martiniwelsondion/357utvl12rsd/wish/166497534
