Using Optical Tweezers for the Generation of Hybrid Spheroids
Research Overview
2D culture still dominates preclinical cancer research even though 3D models better reproduce architecture, microenvironment, and drug response. Optical trapping uses focused laser beams to manipulate position, motion, and interaction of structures at nano- and microscale without touching them — a technique widely used in cell biology but undervalued in cancer research.
This paper recommends a noninvasive protocol using optical tweezers for generating lymphoma-stromal cell assemblies, bringing precise, contact-free control to the construction of 3D cancer co-culture models.
