The production of micro total analysis (micro-TAS) has been the object of intense efforts by the scientific community in the genetic testing area. The necessity of producing a platform that performs the DNA extraction, amplification and separation is driven by the advantages associated with analysis in miniaturized platforms. Microfluidic platforms offer solutions to many problems that affect traditional genetic analyzes, both for forensic applications and for applications in clinical diagnosis, since it allows the integration of all steps involved in the analysis of DNA in a single device. Besides avoiding manipulation of the sample during analysis, the device uses small volume of sample and reagents and provides analysis in a reduced time. In search of the consolidation of this concept, this research project aims to produce polyester-toner (PT) microfluidic platforms fully integrated genetic analysis that allows the extraction, amplification and DNA separation in a single platform - a real "lab on a chip ". In addition to developing the platform is intended to develop some methodologies for application of the device. A method will be developed for detection of bacteria resistant to antibiotics from the class of beta-lactam and a method for clinical diagnosis of neglected diseases by DNA analysis (AU)
