This study investigated biosensors based on the human chromosome (CH22 sequence. The results showed that the electronic and spin transfer of the CH22 sequence is strongly dependent on the frequency and amplitude of incident light and mechanical stress. Accordingly, within the specified frequency domain of 4 to 5 terahertz (THz), the system demonstrates the CH22 capability to transfer the maximum electric current. Furthermore, upon the application of longitudinal stress quantified strain which is denoted by (S1=4), it is observed that the system facilitates the transmission of the maximal spin current. Furthermore, this study showed the emergence of a region of negative differential resistance in response to bias voltage changes, a phenomenon that does not occur in the absence of incident light and DNA tilt, even when mechanical stress is applied. Also, the results showed that positive mechanical stress has a better effect on the formation of spin flow than negative stress. Medical diagnostic tools based on spin polarization have a special place in medicine. By accurately controlling the parameters affecting electrical and spin transport, these sensors can detect biomolecular changes with high sensitivity in biological environments, which can create a fundamental change in the design of modern medical monitoring systems.
