ABSTRACT
Potential bacterial polyhydroxyalkanoates (PHAs) have been drawing considerable attention as biocompatible plastics for a wide range of applications. Several companies are developing PHAs for use in the plastic industry. Currently, Metabolix (USA) and Kaeka (Japan) are among the few companies have actively teamed up for the commercialization of PHA biopolymers known as Nodax. This product has already been made into a variety of different prototype objects such as plastic fiber or twine and molded plastic-ware. PHA could chemically modify their functional groups as well as their biodegradability and biocompatibility properties, making them attractive material in the biomedical field. PHAs are mainly composed of different chiral hydroxy acids that have potential as synthons for anticancer drugs, anti-HIV drugs, antibiotics, and vitamins. Silver nanoparticles (SNPs) have attracted much attention because of their antibacterial properties. The dominant use of SNP is in the cosmetics, antibacterial-water filters and as drug carrier.
