1. A portable handheld wireless device for biomolecule detection comprising:
- an electrophoresis unit comprising;
a sample inlet;
a filter in fluid communications with the sample inlet;
an electrophoretic gel in fluid communications with the filter;
a plurality of immobilization regions serially spaced apart from one another along a separation pathway within the electrophoretic gel; and
opposing electrodes for providing an electric field that defines the separation pathway through the electrophesis gel unit and through the immobilization regions;
an optical source irradiating light to the electrophoresis unit, wherein the electrophoresis unit is sized, shaped, and arranged on the portable handheld wireless device so as to receive light irradiating from a screen of the portable handheld wireless device during operation;
a conversion unit comprising a plurality of detectors optically aligned with corresponding immobilization regions in the electrophoretic gel in which the optically aligned detectors are configured to physically respond to changes in light that transmits through the immobilization regions and strikes onto corresponding optically aligned detectors which in turn drives production of corresponding electrical signals; and
a lead-out unit receiving, converting, and transmitting the electrical signals.
