Biosensors for bioengineering

Drug discovery pathway relies heavily on in vivo animal models and in vitro cell mediums. In the case of animal models we have not only some ethical problems but also the ability to extrapolate data to human conditions is limited and in vitro platforms often do not simulate the complex cell–cell and cell–matrix interactions crucial for regulating cell behaviour.

The Biosensors for Bioengineering group is focused in a new line of research that has become of extreme importance in the last years. The idea is to integrate biosensor technology and nanotechnology with stem cell research and with tissue engineering. Engineered tissues are integrated with biosensing technology to obtain microdevices for detecting cellular responses to external stimuli, monitoring the quality of the microenvironment (e.g., metabolites, nutrients), and supporting diverse cellular requirements. This research on 3D-functional engineered tissues is expected to develop knowledge of tissue construction and their functions and relation with some human diseases. Integration of fully functional tissues with microscale biosensor technology allowed us to obtain “organs-on-a-chip”. These chips could be used in pharmaceutical assays and could be a step toward the ultimate goal of producing in vitro drug testing systems crucial to the medicine and pharmaceutical industry.
