Development of an optical recognition system with microfluidics manipulation for real-time analysis of blood samples, drug delivery inside artificial arteries and 3D reconstruction of microfluidics, fluid analysis and particle tracking. It also includes the development of artificial transparent arteries for medical studies.

Here you can find some extra detailed information regarding our work presented at PAHCE 2013, one related to Artificial Arteries and the other one related to Living-microorganism biomicrosystems.

Abstract -This work studied the mixing behavior of a foreign substance entering into the blood stream. For this study, artificial muscle arteries were designed and manufactured  with diameters from 75 μm to 930 μm. The interaction of substances such as water, blood and serum was studied. After the devices were fabricated, the study was conducted using a characterization platform that consisted on a precision micropump module and an optical system which delivers high-res frame by frame information, and realtime moving microscopic samples.

Abstract - The care and protection of world resources propose nowadays new challenges and compromises, which require a rapid action to assure future availability. Constant efforts have been made to control changes that might affect life; continuous surveillance plays a key-role on environmental conservation and different methods had been used to determine the quality of such resources. The aim of the current research is the design of an easy to use, yet cheap, biosensor, based on electrical properties of different microorganisms, confined in a suitable microestructure.

If you wonder how artificial arteries were produced by our group do not loose the opportunity to see the real deal. CMUA is proud to present the behind the scenes of Artificial Arteries.

Do you want to know how the technology of living-microorganism microsystems was made possible do not loose the opportunity to see CMUA's behind-the-scene of Living microorganism biomicrosystems.

 This is how real blood (mainly red-blood cells) runs inside the artificial arteries. The one shown in the following image has a width of 100 um.
