Abstract
Background: Poly (lactic acid) (PLA) based novel constructs have been engineered for targeted applications in various biomedical sectors of the modern world. In this context, a special focus has been given to pharmaceutical and cosmeceutical industries.
Methods: In this review, we extensively reviewed, analyzed and compiled salient information from the authentic bibliographic sources including PubMed, Scopus, Elsevier, Springer, Bentham Science and other scientific data-bases. A focused review question and inclusion/exclusion criterion were adopted to appraise the quality of retrieved peer-reviewed research literature.
Results: Recently, bio-based constructs are being engineered for target applications in different bio-and non-bio sectors of the modern world to address the growing human health-related serious concerns. The utilization of properly designed and structured materials thus allows the creation of a well-defined environment that induces a series of directed measures, and so on. Over the last few years, PLA-based novel constructs have received exceptional attention as potential candidates for various biotechnological and biomedical applications at large and drug delivery in particular. Owing to their unique characteristics including biocompatibility, together with the adjustable thermo-mechanical and tunable control drug release, PLA has raised interesting applications in many sectors of the medical world. So far, many of such PLA-based bio-constructs have been exploited in drug delivery systems, cosmeceutical products, and therapeutic uses. In recent years, many new applications have been reported for PLA-based materials at the micro-and nano-level, resulting in novel requests for specific drug delivery and cosmeceutical sectors.
Conclusions: In summary, this review summarizes recent research on different aspects of PLA and PLA-based novel constructs and their potential biomedical applications. Moreover, with the aid of nanotechnology, PLA has made a positive impact in emerging sectors such as cosmetics, drug delivery technologies, and healthcare advances.
