This internship propose to explore the hidden world of complex fluids at the single-molecule level. Traditional rheometers only reveal bulk properties, missing the microscopic details that truly govern how polymers move and interact—especially in biologically relevant environments such as mucus transport, where long mucin chains meet arrays of cilia. Using nanopore technology and fluorescence microscopy, you’ll directly visualize individual DNA molecules as they pass through nanometer-sized channels under controlled pressure. From these experiments, you’ll uncover key insights into polymer dynamics and fluid rheology by measuring translocation times, event frequencies, and critical pressures. You’ll be actively involved in setting up and calibrating the experimental system, preparing samples, and analyzing data in both Newtonian (water, water–glycerol) and non-Newtonian (DNA, PEO) fluids.
