摘要:
The invention is a biochemical sensing device, including a photodiode capable of sensing the light generated by the reaction made by a specific compound, a specific enzyme, and a luminol as well as converting the optical signal into a current signal. Also, there is a current/voltage converting circuit capable of converting the current signal into an analog voltage signal. In turn, the analog voltage signal can be converted into a digital voltage signal through an analog/digital converter. Finally, by using an electronic device, the digital voltage signal can be received and analyzed, and through the analysis, the amount of the specific compound can be measured. The device of the invention can provide a simple real-time medical assay that can be performed in massive amount. For this reason, the drawbacks of a conventional spectrum analysis instrument of being bulky and expensive can be improved.
摘要:
A method that modifies surface properties of a substrate by manipulating the immobilized biomolecules in mild biological condition. The manipulation comprised steps of: providing a biomolecule combined with at least one ssDNA combined with a first protein through an affinity binding tag; adding a second ssDNA conjugated with a second protein with a concentration greater than that of the first protein; and replacing the first protein on the ssDNA with the second protein through chemical competitive principle. The invention may comprise the steps with proper design of biotinylated DNA probes, the functionalized ssDNA nanotemplates can be recovered to its unbound state through a thermodynamic principle.
