Conduct Research

Polylactic acid, (polylactide, PLA) polymers are being used in a wide range of biomedical, com-mercial, pharmaceutical and academic applica-tions due to their biocompatibility and biodegra-dability. Applications include stents, sutures and a wide range of uses in food packaging and dis-posable...

...of as one that would "do no harm." The operative principle was that of inertness as reflected, for example, in the definition of as "the quality of not having toxic or injurious effects on biological systems. " A cartilage repair unit injection molded from biodegradable polylactide (PLA). When...

...devices, a great deal of research continues on polyanhydrides, polyorthoesters, polyphosphazenes, and other biodegradable polymers. A biodegradable intravascular stent prototype is molded from a blend of polylactide and trimethylene carbonate. Photo: Cordis Corp. Prototype Molded by Tesco Associates, Inc...

...with two new biocontent polycarbonate blends containing polylactide (PLA), a polymer derived from plant materials. Makroblend BC250 and BC400 are general-purpose grades that contain 25 and 40% PLA, respectively. The biocontent grades can serve in applications such as cell phones and smart phones...

...of consumer packaging made from common plastics such as PET and polypropylene (PP) to those associated with polylactide (PLA), a widely used corn-based plastic. Athena's study looked strictly at five packaging items: 16-oz cold-drink cups, two-piece deli containers, envelope window film, foam meat...

...more pliable than other bioplastics, making them easier to mold. Bioplastic blends can replace only about 20 percent of the polyethylene in a product, so resulting materials are only partially biodegradable. But Onwulata and his colleagues are currently applying this process to polylactide (PLA...

...with synthetic degradables. Conventional synthetics used in implants include polylactides, polyglycolides, and polyhydroxybutyrates. But these materials are difficult to make into injection-moulded structures with good mechanical properties because of their sensibility to moisture and temperature...

...the effectiveness of the implants in eight 12-month-old sheep. Surgical templates were used to create artificial skull defects that measured 4.5 x6.5 cm. Composed of polylactides, calcium phosphate, and calcium carbonate, the implants are prepared in a single mould using a combination of processing...

Crystalline Sensors. Polylactide containing caffeine and an optical code. Normally colorless, the polymer picks up a characteristic color when cast in a nanostructured porous template consisting of a silicon photonic crystal. Color decay can be monitored through tissue to provide a marker of the amount...
