This study presents the state of the art by introducing what has been innovated and patented concerning cellulose-based biosensors between 2010 and 2020. More specifically, this form of patent analysis encapsulates information that could be used as a reference by researchers in the fields of biosensors and cellulose-based biosensing platforms, as well as those interested especially in cellulose and its derivatives. As a result of this study, a total of 241 patent documents related to cellulose-based biosensors were found. The United States leads the patent race in this sector. Based on patent classifications, most patents and inventions are intended for chemical analysis of biological materials and testing involving biospecific ligand binding methods, as well as measuring or testing apparatus with condition measuring or sensing means. Research and development are based on the investigating or analyzing of materials by the use of electric or electrochemical means, as well as nanotechnology for interacting, sensing, or actuating, which are concentrated in most patents.","PeriodicalId":220042,"journal":{"name":"The 2nd International Electronic Conference on Biosensors","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122876292","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}

Tsekenis","doi":"10.3390/iecb2022-12273","DOIUrl":"https://doi.org/10.3390/iecb2022-12273","url":null,"abstract":": Wearable biosensors for the detection of analytes in sweat are an emerging and promising technology with important applications in monitoring a person’s physiological state. Sweat, being an easily accessible biofluid, shows great potential as a biological fluid for wearable devices, but also a number of challenges that must be addressed before a sensor can be commercialized. As an example, sensor fabrication on flexible substrates can greatly affect the performance of the device. Herein, the development of an enzymatic electrochemical sensor on a flexible substrate for glucose detection is presented. The sensor’s three-electrode systems were made entirely with carbon-based ink on polyimide substrates and decorated with carbon black. The developed and optimized sensor design exhibited a stable and reproducible performance and was able to detect glucose in concentrations relevant to the ones present in sweat.","PeriodicalId":220042,"journal":{"name":"The 2nd International Electronic Conference on Biosensors","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132131416","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}

Therefore, we investigated the use of MAX30102, a commercial photometric biosensing module coupled to a ESP32 system-on-a-chip and its internet-of-things capabilities to continuously gather and process peripheral oxygen levels (SpO 2 ) and heartrates (HR) from users. Moreover, a user-friendly graphic interface was designed and implemented, and an anatomical case was 3D printed in thermoplastic polyester. Results showcased that the device functioned reliably, and according to literature describing photometric sensor functioning, thereby shedding light on the use of simple and affordable electronics for developing biosensing","PeriodicalId":220042,"journal":{"name":"The 2nd International Electronic Conference on Biosensors","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724071","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}
