Multi-Cellular Aggregation using Optical Traps

Multi-cellular aggregation is a fundamental phenomenon observed in many biological processes. Investigating cells aggregation helps us to have better understanding of many biological processes. Moreover, it is useful in finding cure for the diseases caused by cells aggregation. In this paper, we present a control methodology to obtain multi-cellular aggregation by using multiple optical trapping. The proposed method is also useful for study of multiple cell fusion which is an important cellular process. Experimental results are presented to show the effectiveness of the proposed method in achieving multi-cellular aggregation.
