Article Synopsis
- The study focuses on creating an electrochemical immunosensor to detect the pathogenic bacteria Staphylococcus aureus, addressing concerns related to biological threats, hospital infections, and food safety.
- The immunosensor was developed using anti-S. aureus antibodies immobilized via a self-assembled monolayer technique on a gold surface, and its functionality was evaluated using electrochemical methods like cyclic voltammetry and electrochemical impedance spectroscopy.
- Results showed a linear relationship between electron transfer resistance and S. aureus concentration (10 to 106 CFU/mL), with a limit of detection at 10 CFU/mL and high selectivity against E. coli and S. epidermidis, confirming the sensor's
Two cement pastes, commonly used in concrete formulations, were characterised by IGC at 35-80 degrees C before and after coating with an epoxy resin and a hardener. The cements are mixtures of hydrates in various proportions, such as calcium silicate hydrate (CaO-SiO2-H2O) and calcium hydroxide Ca(OH)2. Apolar and polar probes were used to determine the dispersive and acid-base characteristics of the cement pastes.
