WebMar 4, 2011 · Microrheology is a branch of rheology having the same principles as conventional bulk rheology, but working on micron length scales and microlitre volumes. Optical tweezers have been successfully used with Newtonian fluids for rheological purposes such as determining fluid viscosity. Websample, are often used in optical tweezers instruments. These can have numerical apertures of up to 1.4. The use of high power lasers also maximizes the trapping force. An alternative optical tweezers design that can easily overcome the loss due to reflection at the bead surface uses a dual-beam design, shown in Figure 4.
