Joseph Wang (born 1948) is an American biomedical engineer and inventor. He is a Distinguished Professor, SAIC Endowed Chair, and former Chair of the Department of Nanoengineering at the University of California, San Diego, who specialized in nanomachines, biosensors, nano-bioelectronics, wearable devices, and electrochemistry.
In amperometric biosensors, an enzyme-catalyzed redox reaction causes a redox electron current that is measured by a working electrode. [11] Amperometric biosensors have been used in bio-MEMS for detection of glucose, galactose, lactose, urea, and cholesterol, as well as for applications in gas detection and DNA hybridization. [11]
Another cancer related application, though still in mice probing stage, is the use of peptide-coated nanoparticles as activity-based sensors to detect lung cancer. The two main advantages of the use of nanoparticles to detect diseases is that it allows early stage detection, as it can detect tumors the size in the order of millimeters.
[77] [78] Development of wearable biosensors is among such studies. [79] The elimination of lab testing can save time and money. An application of a POCT biosensor can be for the testing of HIV in areas where it is difficult for patients to be tested. A biosensor can be sent directly to the location and a quick and easy test can be used.
Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...
Biosensors detect what the user wants to do or their intentions and motions. In some devices, the information can is relayed by the user's nervous or muscle system . This information is related by the biosensor to a controller , which can be located inside or outside the biomechatronic device.
The World Congress on Biosensors continues today. According to the Journal Citation Reports, the journal has a 2023 impact factor of 10.7 [1] 5-Year Impact Factor: 9.323 [2] Biosensors & Bioelectronics is the principal international journal devoted to research, design, development, and application of biosensors and bioelectronics.
A smart wearable system (SWS) is an end-to-end integrated and connected system that has the following features: one or more sensors and actuators nodes at the end-user side and possibly integrated into worn items
