ResumenLos Polihidroxialcanoatos (PHA) son plásticos biocompatibles y biodegradables sintetizados por una amplia variedad de microorganismos, que comparten características muy similares con los plásticos de origen petroquímico. Los estudios más recientes se centran en la búsqueda de sustratos económicos y en estrategias de extracción que permitan la reducción de los costos del producto y de esta forma, puedan incursionar en un mercado ampliamente difundido donde dominan los plásticos derivados del petróleo. El objetivo de esta revisión, consiste en mostrar la producción de polihidroxialcanoatos como un recurso y herramienta de primera mano que tienen un gran potencial de uso en aplicaciones que van desde la manufactura de productos desechables de uso común, hasta la de productos biomédicos y farmacéuticos de alto valor agregado.Palabras clave: bioplásticos; biopolímeros; polihidroxialcanoatos; microorganismos; biosíntesis. AbstractPolyhydroxyalkanoates (PHA´s) are biodegradable and biocompatible plastics synthesized by a wide variety of microorganisms, which share similar characteristics with petrochemical plastics. The most recent studies focus on the pursuit of economic substrates and extraction strategies that allow reducing product costs and thus, can make inroads in a market widely disseminated where petrochemical plastics dominate. The aim of this review is to show the polyhydroxyalkanoates production as a resource and tool first hand and have great potential for use in applications ranging from the manufacture of disposable products commonly used to biomedical and pharmaceutical products high added value.

This article aims to show how the bioglass has been important in the development of biomedical sciences from its applicability and versatility in its multiple uses. This review aims to show how through interdisciplinary research it has designed different processes for obtaining materials from bioactive glasses. First, we will discuss the importance of development of biomedical devices focused in bioglass as precursor material and its impact on society today. Subsequently, relevance and importance of the surface modification as mechanism to improve working Review of biocompatibility behavior of bioglass as promising material in biomedical industryRevisión del comportamiento biocompatible de biovidrio como material promisorio en la industria biomédica
