Abstract

In classical DNA chip analysis, the target DNA moves by diffusion and Brownian motion only. We introduce a system for enhancing the signals and reducing the hybridization times of bio chips. It allows active agitation within the hybridization buffer by controlled movement of magnetic particles within the analyte solution. First results show that the system easily achieves specific fluorescent signals about four times higher than the ones obtained by a referencing standard procedure within the same hybridization time, while unspecific signals remain unchanged. The device can easily be applied to existing bio chip applications and allows universal operation in the field of molecular diagnostics.
