1. 6. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Hiruy Michael Weldegiorgish; [2022]
   Keywords : Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

   Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

3. 7. BIOMIMETIC SENSORS FOR RAPID AND SENSITIVE SARS-CoV-2 DETECTION

   University essay from Malmö universitet/Fakulteten för hälsa och samhälle (HS)

   Author : Maryam Hmouda; [2022]
   Keywords : ;

   Abstract : In the last two years, the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has impacted the entire world. SARS-CoV-2 detection methods include Polymerase Chain Reaction (PCR), which is expensive, and Rapid Antigen Test, which is not highly sensitive. READ MORE

4. 8. The differential signalling of the succinate receptor SUCNR1/GPR91, through Gi versus Gq

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Sofie Liljewall; [2022]
   Keywords : GPR91; SUCNR1; G protein recruitment; Gi; Gq; TRUPATH biosensor; BRET2; Applied Microbiology; Biology and Life Sciences;

   Abstract : G protein-coupled receptors are the biggest family of membrane bound receptor in the human genome, they are also target for many drugs due to their accessible location in the cell membrane. We have characterized the G protein recruitment of the succinate receptor 1 (SUCNR1/GPR91). READ MORE

5. 9. OPERATION OF AN ELECTROCHEMICAL BIOSENSOR DEVELOPED FOR COVID-19 DETECTIONIN SARS-COV-2 FREE AND INFECTED HUMAN SALIVA

   University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV); Malmö universitet/Biofilms Research Center for Biointerfaces

   Author : Bashir Wakil; [2022]
   Keywords : x;

   Abstract : The demand for the improvement of currently available tests for qualitative non-invasive diagnostic of COVID-19, i.e., the development of new methods for fast, low-cost and accurate tests for the conformation of SARS-CoV-2, is increasing rapidly. READ MORE

6. 10. Validation of anti-cytokeratin antibodies used in rapid cancer diagnostics by isoelectric focusing and QCM technology

   University essay from Uppsala universitet/Biokemi

   Author : Reneh Kostines; [2021]
   Keywords : IEF; Isoelectric focusing; QCM; Attana; Cytokeratin; Keratin; Attana; Anti-cytokeratin; cancer; UBC; IDL; epithelial carcinomas; Antibody validation; Biosensor; Biosensors;

   Abstract : Antibodies are Y-shaped proteins. In the human body, antibodies areproduced by plasma cells, mainly T and B cells which are included inthe adaptive immune system. The production of antibodies is stimulatedby antigens. The binding between an antigen-specific antibody and itsantigen can be like the interconnect between a lock and a key. READ MORE
