The hydrodynamic drag force on a spherical particle in shear flow near-wall is investigated
using optical tweezers and microfluidics. Simple shear flow is applied using a microfluidic …

In the study of micro-scale biological flows, velocimetry methods based on passive tracers,
such as micro-PIV and micro-PTV, are well established to characterize steady flows …

Lab-on-a-chip devices have become useful to study substances not available in
macrometric amounts. To manipulate the substances under study, ways to induce flow within …

The lack of a suitable experimental setup and a limited number of in vitro investigations have
impeded understanding of the factors that have important roles in altering the drag force …

An optical tweezers applications are becoming vast over time due to its unique ability to
optically trap micron sized objects. However, calibration in term of optical stiffness …

Obtaining trap stiffness and calibration of the position detection system is the basis of a force
measurement using optical tweezers. Both calibration quantities can be calculated using …
