An integrated microfluidic platform for chromosomal analysis

The fluorescence in situ hybridization (FISH) technique has been commonly employed to determine chromosomal abnormalities. However, it still requires lengthy and labor-intensive sample preparation process. In this study, a new microfluidic chip capable of performing the entire FISH protocol automatically was reported. When compared with the traditional method, several advantages including reduced consumption of biosamples and reagents, automation, fast analysis, can be achieved. Experimental data demonstrated that the developed system can successfully provide superior performance for probing the genetic content of cells at the chromosomal abnormality.
