Making changes of cells function by regulating the external mechanical environment is one of the major interests in the mechanobiology field. Based on extensive studies, force at nano-to-micro newton and geometric shape changes at nano-to-micrometer are the physical stimuli that can be sensed by cells. It has been postulated that controllable cell responses can be produced by activating diversity...
Mechanical force sensing is an important and integral component in the study of the viscoelastic properties of biological cells. In this study, a vision-based non-contact force sensing technique for real-time stressing of biological cells by a vision-guided robotic micromanipulation system is introduced. The system is capable of providing real-time external mechanical stressing on biological cells...
Biological cells possess biochemical modules and physical shapes to maintain appropriate biological function. Different types of force and deformation are applied on cells to investigate the response and mechanical properties. In the biophysics field, studies use indentation deformation on cell membranes to examine the elastic-viscoelastic properties of biological cells. Experiments in different predefined...
Microwave radiation has a variety of biological effects. In this study, the biological effects of microwave radiation on a marine alga Nannochloropsis oculata were investigated. The results showed that the electrolyte leakage in the microwave treated group was increased 107.7%, compared with the untreated group. A significant increase (P<;0.01) of the activity of superoxide dismutase by 20.6%,...
