These materials have a wide range of potential applications including use in polyurethanes and specialty products. Discovery, Reactivity, Optimization, and Mechanism. PLLA discs were seeded with rat hepatocytes in a concentration of 2.
Optimization of Hepatocyte Spheroid Formation for Hepatic Tissue Engineering on Three-Dimensional Biodegradable Polymer within a Flow Bioreactor prior to Implantation We hypothesize that in vitro conditioning of hepatocytes within biodegradable poly-L-lactic acid PLLA polymer matrices prior to implantation may increase hepatocyte survival and function after transplantation.
For years, there has been excitement in the scientific community about the possibility of paper-based batteries as an eco-friendly alternative. SphA of Research paper on biodegradable polymer cultured with this flow bioreactor method may prove useful as a functional unit for tissue engineering of an in vivo liver substitute.
The number of SphA was examined by phase contrast microscopy and the reductive enzyme function of the hepatocytes was tested using MTT.
A New Polymer Stereocomplex. Stereocomplexed Poly Limonene Carbonate: The team tested the degradation of the battery in water and it clearly biodegraded without the requirements of special facilities, conditions or introduction of other microorganisms.
Our goal is to develop an alternative synthetic route that consists of carbonylation of epoxides to beta-lactones, followed by ring-opening polymerization to yield PHAs. The team said that producing the biobatteries is a fairly straightforward process and that the material allows for modifications depending on what configuration is needed.
The polymers—poly amic acid and poly pyromellitic dianhydride-p-phenylenediamine - were the key to giving the batteries biodegrading properties. However, the proposed designs were never quite powerful enough, they were difficult to produce and it was questionable whether they were really biodegradable.
August 8,Binghamton University Researchers at Binghamton University, State University at New York have created a biodegradable, paper-based battery that is more efficient than previously possible.
Polyesters Our group has developed zinc, chromium, cobalt, and aluminum catalysts for the alternating copolymerization of epoxides and cyclic anhydrides. Recently, we reported a one-pot carbonylative polymerization method that makes poly 3-hydroxybutyrate PHB from propylene oxide and carbon monoxide.
This new design solves all of those problems. The purpose of this study was to optimize the culture conditions of hepatocytes in a pulsatile flow bioreactor. Choi said that flexibility also provides another benefit. Hematoxylin and eosin histology showed vital hepatocytes within the SphA less than microm in diameter but central necrosis in the SphA exceeding this size.
The purpose of this study The polymer-paper structures are lightweight, low-cost and flexible. Only under flow conditions the hepatocytes formed spheroidal aggregates SphA of microm in diameter with a liver-like morphology and active metabolic function.
Choi engineered the design of the paper-based battery, while Sadik was able to make the battery a self-sustaining biobattery.
Poly hydroxyalkanoates Poly hydroxyalkanoate s PHA s are naturally-occurring biodegradable polyesters made by bacterial fermentation. Researchers at Binghamton University, State University at New York have created a biodegradable, paper-based battery that is more efficient than previously possible.
Immunohistochemical staining confirmed albumin production of hepatocytes within the SphA. We can synthesize an array of diverse structures with widely varying properties, ranging from semi-crystalline stereocomplexed poly propylene succinateto completely amorphous high-Tg terpene based materials, to polyester-b-polycarbonate block copolymers via a one-pot terpolymerization.Research.
