“…7 The methods to obtain various PHAs in the laboratory using various bacterial species are summarized in our earlier publication. 8 Among these, PHB and PHBV are used most extensively for biomaterial investigations; hence, PHAs are commercially available. The various applications include biomedical applications such as drug delivery, development of scaffolds, implants, and biosensors, 9 food coating, packing, agriculture, molded goods, non-woven fabrics, adhesives, textile, paper coating, automobiles, performance additives, [10][11][12][13][14] energy materials, etc.…”

Polyhydroxyalkanoates (PHAs) are biopolymers synthesized by bacteria under unbalanced growth conditions. These biopolymers are considered as potential biomaterials for future applications because they are biocompatible, biodegradable, and easy to produce and functionalize with strong mechanical strength. Currently, PHAs are being extensively innovated for biomedical applications due to their prerequisite properties. The wide range of biomedical applications includes drug delivery systems, implants, tissue engineering, scaffolds, artificial organ constructs, In this article we review the utility of PHAs in various forms (bulk/nano) for biomedical applications so as to bring about the future vision for PHAs as biomaterials for the advancement of research and technology.

“…Growing environmental concerns of persistent plastic wastes have prompted the development of biodegradable and biocompatible polymers, which can be decomposed by living organisms without harming them and the environment. − Among these polymers, poly(hydroxyalkanoates), such as poly(3-hydroxybutyrate) (PHB), a biodegradable aliphatic polyester, have attracted significant attention in applications ranging from green packaging to drug delivery systems. − To further their applications, it is essential to control the polymer architectures, which can directly affect the physical properties. Ring-opening polymerization (ROP) of cyclic esters and ring-opening copolymerization (ROCOP) of epoxides and cyclic anhydrides are promising techniques for the synthesis of polyesters in a well-controlled fashion, and a wide range of catalysts have been developed .…”

A series of amido-oxazolinate zinc complexes have been employed for the ring-opening polymerization of rac-β-butyrolactone (BBL). Experimental results show that these complexes efficiently catalyze the reactions, yielding cyclic poly(3-hydroxybutyrate)s (PHBs) with high molecular weights (M n up to 197 kg/mol) and relatively low dispersity. In comparison, in the presence of alcohol cocatalysts, the zinc-catalyzed ROP reactions lead to the formation of linear PHBs end-capped by the alcohol initiator and hydroxylbutyrate. A possible mechanism for cyclic PHBs is proposed, in which the zinc catalysts function as a loose Lewis pair at elevated temperature, followed by a fast propagation through a zwitterionic intermediate. Use of diols such as 1,4-cyclohexanediol and 1,4-benzenedimethanol results in the formation of telechelic polyester diols. The thermal analysis by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) shows higher thermal resistance of cyclic PHBs than linear ones.

The methods available for the disposal of synthetic polymers are not advanced in an environment-friendly way. Consequently, their waste persists as a non-degradable pollutant that discharges toxic substances, which have now reached the deepest parts of the ocean. As an alternative, biopolymers such as polylactic acid, polyhydroxyalkanoates, and poly(butylene succinate), synthesized from natural sources such as plants, animals, and microbes, are an eco-friendly option, as they are biodegradable and a better option to shift from synthetic polymer dependency. The fabrication of electrospun nanofibers (NFs) using biopolymers is a novel approach, by which new ideas have been proposed in various fields, such as agriculture, biomedical, food packing, textiles, adsorption, drug delivery, three-dimensional printing, etc. Electrospun NFs are receiving increasing attention due to their diverse properties, including flexibility. This review provides a perception of the novel biopolymers that are currently utilized by the electrospun technique and their various applications.
