Marker-free cell discrimination by holographic optical tweezers [PDF]

Journal of the European Optical Society-Rapid Publications, 2009
We introduce a method for marker-free cell discrimination based on optical tweezers. Cancerous, non-cancerous, and drug-treated cells could be distinguished by measuring the trapping forces using holographic optical tweezers.

Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment. [PDF]

J Cell Physiol
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.
