Lab-on-a-chip for microfluids applications

Graca Maria Henriques Minas

Department of Industrial Electronics
University of Minho, Guimaraes

Lab-on-a-chip for microfluids applications that uses acoustic waves to promote the mixing and the movement of the fluids. The transducer that generates the acoustic waves is a piezoelectric polymer that we can process to be functionally graded for, in conjunction with the applied signal to the transducers, controlling the bombing direction and added heating. A highly selective thin-films optical filtering system allows the use of only a white light source when spectrophotometry is used as the detection technique resulting in a really portable device. Such Lab-on-a-chip devices can provide a plataform that allows reduce sample size, higher degree of integration and hence enhanced potential for automation, shortened response time, potential for improved analytical performance, reduced laboratory safety and costs. Therefore, they can contribute to a better quality in the health care services and also a better efficiency in the clinical and administrative processes.

Brief Bio:

G. Minas graduated in industrial electronics engineering in 1994, received the M.Sc. degree in 1998, and the Ph.D. degree in 2004, all from the University of Minho, Guimar\E3es, Portugal. Her thesis work was in cooperation with the Laboratory for Electronic Instrumentation, Delft University of Technology, Delft, The Netherlands, and dealt with lab-on-a-chips for biological fluids analysis. Between 1995 and 2004 she was a Lecturer, between 2004 and 2010 Assistant Professor, and since 2010 she is Associate Professor at the Department of Industrial Electronics, University of Minho, where she is involved in biomedical microdevices research. Her research is basically focussed on lab-on-a-chip devices for microfluids mixing with on-chip integration of electronic circuits, optical filters, sensors, biosensors and microactuators.
