Uso de blendas poliméricas como sistema de vetorização de fármacos para cicatrização : prospecção tecnológica

Abstract

The biopolymers, polymeric materials of natural origin or synthetic, are used for biomedical applications. Among the universe of applicability relating to polymeric biomaterials, tissue engineering is presented as a major investor in research that will develop ways to stimulate the regeneration of skin lesions. The objective of this research was to conduct a survey on the use of technology polymer blends for healing, performing a search for patent applications in the filings of domestic and international patents. Prospecting was carried out based on the patent applications filed in the database of the National Institute of Industrial Property (INPI) of Brazil, the European Patent Office (EPO), United States Patent and Trademark Office (USPTO) and the World Intellectual Property Organization (WIPO). After prospecting was found only in 2004 with the rank of section C08 (Chemical, Metallurgy) and A61K (Human Needs). To date there are a number of patents associated with deadpan polymer blends and healing, we analyzed databases, but when separated these terms take on a significant amount. Thus, it was concluded that there is a lack of patents and scientific studies on this association, requiring more research on the topic.
