Abstract
We report an in situ method for temperature measurement in microfluidic systems using Brownian diffussion of nanoparticles. This method is superior in its reproducibility and reduced systematic errors as measuring Brownian diffusivity does not rely on fluorescence intensity or lifetime of fluorophores. Threedimensional temperature mapping was achieved using a simple videomicroscopy setup in combination with software analysis that enables selective tracking of nanoparticles. In addition, we successfully demonstrated the capability of this method as an in situ noninvasive temperature measurement tool for biological samples.
