亲和型传感器、特别是QCM传感器
By designing the interface between the nanoscale region and the passivation region, the adsorption of analytes is restricted to the nanoscale region, thus solving the problem of the unknown influence of nanopatterns on adsorption and improving the adsorption quality and sensitivity of the sensor.

AI Technical Summary
In the prior art, it is not yet clear how nanopatterns affect the adsorption of solutes, and it is difficult to confine adsorption events to a predetermined molecular size region, especially for high-density analysis and measurement on relatively large surfaces.
Design an affinity sensor comprising an interface between nanoscale regions and passivated regions, wherein the nanoscale regions are separated by passivated regions to restrict the adsorption of analytes within the nanoscale regions, and the nanoscale regions occupy at least 15% of the surface area of the interface, employing a hexagonal lattice arrangement and selective functionalization.
It significantly affects acceptor density and adsorption kinetics, improving adsorption quality and sensitivity, even with a reduced available surface area, and even exceeding the adsorption quality of unpatterned sensors.
