Prof. Shen and her unit say that, in the future, nanoplasmonic materials may even be integrated with emerging technologies, such as wireless systems in microfluidic devices, allowing users to take readings remotely and thereby minimizing the risk of contamination.
As it can take weeks to grow human cells into intact differentiated and functional tissues within Organ Chips, such as those that mimic the lung and intestine, and researchers seek to understand how drugs, toxins or other perturbations alter tissue structure and function, the team at the Wyss Institute for Biologically Inspired Engineering led by Donald Ingber has been searching for ways to non-invasively monitor the health and maturity of cells cultured within these microfluidic devices over extended times.
Chemist John Pojman of Louisiana State University in Baton Rouge adds that such roving droplets «might be useful as a pumping mechanism for microfluidics, converting chemical energy to mechanical motion in small devices,» such as the microfluidic labs - on - a-chip many researchers are developing as diagnostic machines.
Wardle says the combination of carbon nanotubes and multilayer coatings may help finely tune microfluidic devices to capture extremely small and rare particles, such as certain viruses and proteins.
«WPI brings an outstanding theoretical tool that allows us to understand how microscale objects, such as sperm, interact with their environment; and we are able to design this know - how into real microfluidic devices, clinically validate what we designed, and experimentally improve it into a real - world application.»
In their article, the teams describe how they used the process to etch patterns of hollow channels like those used to direct the flow of liquids, such as a blood sample, in a microfluidic device, or lab on a chip.
«These highly elusive 3 - nanometer structures are too small to be captured with other types of liquid biopsy devices, such as microfluidics, due to shear forces that can potentially destroy them,» he noted.
In order to develop a system that more closely replicates the metabolic differences among hepatocytes, the research team developed a microfluidic device that distributes hormones or other chemical agents across a 20 - to 40 - cell - wide sample of hepatocytes in such a way that the effects on the liver cells vary from one side to the other.
