Abstract

The invention provides a method for constructing a novel counter. The method comprises the following steps: using a cyanine dye solution as a template, using potassium ions as positive counting inputpulses, and using 18-crown-6 as reverse counting input pulses, marking the state of the cyanine dye in a Tris-HCl buffer solution with a concentration of 100*10-3mol / L and a pH of 6.0-9.0 as an initial state of positive counting, then gradually adding equal parts of potassium ions or 18-crown-6, using equal parts of potassium ions as pulse signals of positive counting, using equal parts of chelating agent 18-crown-6 as pulse signals of reverse counting, and using a cyanine dye aggregation state induced by each pulse signal as a parallel output signal to construct the counter. The method is simple and easy to operate, the sensitivity is high, and a multi-bit counting function can be achieved.

Description

technical field [0001] The invention belongs to the technical field of counters, and in particular relates to a construction method of a novel counter. Background technique [0002] Since the birth of the first electronic computer in 1946, electronic computers have realized the transition from tubes to transistors to integrated circuits and large-scale integrated circuits at an astonishing speed. Electronic computers have penetrated into all aspects of life, greatly promoting the development of astronomy, military, simulation and other fields. However, when the silicon conductor integrated circuits of electronic computers are densely packed to a certain extent, problems such as overheating and cross-interference will appear. In 1959, Feynman proposed the idea of ​​using the molecular scale to develop computers. Molecular computers use synthetic organic molecules, supramolecules, and biological macromolecules to build computers at the molecular level. Molecular logic is exp...
