The capability of noninvasive and precise micromanipulation of sensitive, living cells is necessary for understanding their underlying biological processes. Optical tweezers (OT) is an effective tool that uses highly focused laser beams for accurate manipulation of cells and dielectric beads at microscale. However, direct exposure of the laser beams on the cells can negatively influence their behavior...
Studying collective migration of cells is currently of considerable interest in biology and medicine leading to possibility of novel diagnosis and treatments. Some cells are highly sensitive to direct laser exposure, which may influence their behavior or even cause photodamage. In addition, manual manipulation of cells is time consuming making it hard to carry out systematic studies that are properly...
Optical tweezers are used for manipulation of micron-sized dielectric beads and cells. Some biological cells are vulnerable to photo damage if subjected to laser-based direct manipulation. In such cases, precise manipulation of these cells can be accomplished by using gripper formations made up of silica beads, which are actuated by optical tweezers. Manual indirect manipulation of cells using grippers...
Optical Tweezers (OT) are used for highly accurate manipulations of biological cells. However, the direct exposure of cells to focused laser beam may negatively influence their biological functions. In order to overcome this problem, we generate multiple optical traps to grab and move a 3D ensemble of inert particles such as silica microspheres to act as a reconfigurable gripper for a manipulated...
