Patent number: 11597898Abstract: A number analyzing method, a number analyzing device, and a storage medium for number analysis are disclosed, which enable, with high accuracy, analysis of the number or number distribution of particulate or molecular analytes according to the kinds of the analytes. A computer control program is executed on the basis of a data group of particle-passage detection signals which are detected by a nanopore device in accordance with passage of subject particles through a through-hole. Also, a particle type distribution estimating program is executed, to estimate probability density on the basis of a data group based on feature values indicating feature of the waveforms of pulse signals which correspond to the passage of particles and which are obtained as the particle-passage detection signals. Thus, the number of particles can be derived for each particle type.Type: GrantFiled: December 19, 2016Date of Patent: March 7, 2023Assignee: AIPORE INC.Inventors: Takashi Washio, Tomoji Kawai, Masateru Taniguchi, Makusu Tsutsui, Kazumichi Yokota, Akira Ishii, Takeshi Yoshida
