Nano particles on the scales

A wide variety of problems in science and technology is concerned with the study of biological and synthetic nanoparticles. Being less than one hundred nanometers in size, such objects often elude conventional techniques of detection and measurement. Nanofluidic resonators have recently enabled the direct weighing of single nanoparticles and the measurement of size distributions in complex liquid samples. Such measurements are important to help advance our understanding of many fundamental processes in biophysics, medicine, biology, biotechnolgy.
