Nowadays, microfluidic technology is one of the most expanding fields of research, with an estimated world market of about 3 billion dollars in year 2014. It is ambitioned that microfluidics will have a mayor contribution in the life science and biotechnology sectors trough the development of point-of-care (POC) diagnostics, biosensors, devices for cell biology and the environmental, food and agricultural industries.
In order to achieve these goals, the development of fully integrated autonomous micro-fluidic devices is of critical relevance. The lack of robust fundamental building blocks for fluid control and sensing are the mayor drawbacks.[2, 3] Therefore, in these devices, the use of smart valves and pumps is essential for the manipulation and control of flows at the microscale.[5, 6] In addition, smart functional materials with sensing properties, integrable in microfluidics, are necessary to fabricate devices at a lower cost and with high commercial and economical potentials.[7, 8]
Here I review our latest results on the generation of novel microfluidic platforms that integrate smart functional materials with sensing and actuating capabilities.
