The cantilever body is enclosed inside a hydrophobic parylene shell, and a ring-shaped hydrophobic slit is designed to prevent the solution leak inside the shell, allowing the cantilever structure keeps high-Q resonance in air while the binding sensing pool is exposed to aqueous solution for the biological binding. The resonant cantilever continuously records the frequency-shift according to the binding induced mass change on the cantilever. The frequency signal is useful for revealing kinetic/thermodynamic mechanism of the interface binding by fitting the detected sensorgram with classic equations. This detection strategy is label-free and calibration-free, with all the measurement completed using one device to avoid system error.","PeriodicalId":6776,"journal":{"name":"2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"75 1","pages":"88-91"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86273885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The atomization and oscillation of a droplet are separately tested using prepared DFG samples. The droplet atomization remains tiny satellite droplets on the surface of the DFG after the operation, while the droplet oscillation clearly removes the droplet from the surface. The DFG can be used to efficiently clean water and viscous droplets generated on the surface of various optical sensors.","PeriodicalId":6776,"journal":{"name":"2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"3 1","pages":"36-37"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82466971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we demonstrated an example of cell manipulation by using this method. We made a flow channel for cell transportation by irradiating light. We succeeded in making straight channel by irradiating actuators with sheet laser.
