A low cost system for DNA detection
DNA. Electrophoresis gel. Low cost. Molecular spectroscopy.
This work presents a review on the detection methods of nucleic acids and all instrumentation, techniques and theories used in the detection process. The objective of this review is to base a project that consists in the development of a low cost DNA detection system capable of obtaining, through image processing, quantitative data from electrophoresis gel analysis using accessible techniques with potential for rapid diagnosis of samples in the areas of health, agriculture and aquaculture. The proposed device has the ability to go all the color spectrum in order to suit the various gels used commercially. Data analysis on site will be processed in software on the smartphone and then sent to the software in the cloud for analysis and documentation of images of DNA and protein gels. The software will automatically be able to detect the bands, fragment size and molecular weight.
