Synthesis, Structural and Sensor Properties of Nanosized Mixed Oxides Based on In2O3 Particles

Mariya I. I. Ikim et al.

Summary: The paper discusses the correlation between the structure and properties of nanostructured conductometric sensors utilizing binary mixtures of semiconductor oxides to detect reducing gases in the environment. The effectiveness of the sensors depends on the chemisorption of molecules on catalytically active particles and the subsequent transfer to electron-rich nanoparticles, where they react with the analyzed gas. Factors such as composite synthesis method, catalytic activity of metal oxides (CeO2, SnO2, ZnO), and conductivity type of metal oxides (Co3O4, ZrO2) are evaluated in relation to the sensor process. The impact of oxygen vacancies in the composites on performance characteristics is also considered, with particular focus on the synthesis procedure for sensitive layers based on CeO2-In2O3 and their structure, conductivity, and sensing properties.

Biosensors for the Determination of SARS-CoV-2 Virus and Diagnosis of COVID-19 Infection

Maryia Drobysh et al.

Summary: Monitoring and tracking infection is crucial for controlling the spread of COVID-19. To achieve this, the development and deployment of accurate diagnostic methods are necessary. Biosensing devices, such as electrochemical biosensors, that utilize various detection methods and biomarkers are commonly used to detect the SARS-CoV-2 virus. Immunosensors based on antigen-antibody interaction are particularly useful in label-free mode for sensitive detection.

Ultra-selective tin oxide-based chemiresistive gas sensor employing signal transform and machine learning techniques

Snehanjan Acharyya et al.

Summary: In this study, a metal-oxide based chemiresistive sensor was integrated with soft computing tools for selective detection of gases. The sensor exhibited remarkable sensing performance towards various volatile organic compounds (VOCs) with the help of signal processing, feature extraction, and machine learning. The extracted features were inputted into machine learning algorithms to qualitatively discriminate among different VOCs and quantitatively estimate their concentrations. The approach achieved excellent classification accuracy (best average accuracy: 96.84%).

Room-Temperature Detection of Perfluoroisobutyronitrile with SnO2/Ti3C2TX Gas Sensors

Peng Wu et al.

Summary: A Ti3C2Tx-SnO2 nanocomposite sensor shows superior sensitivity, high selectivity, strong anti-interference ability, and excellent long-term stability for room-temperature detection of the gas insulating medium C4F7N. The synergistic effect between SnO2 and Ti3C2Tx, along with the strong adsorption ability of SnO2 to C4F7N, enhances the sensing mechanism. This work demonstrates the feasibility of the Ti3C2Tx-SnO2 sensor for actual engineering applications, providing distribution rules with high sensing efficiency.

RT-PCR diagnosis of COVID-19 from exhaled breath condensate: a clinical study

Makoto Sawano et al.

Summary: The study aimed to quantify the viral load in exhaled breath condensate (EBC) collected from COVID-19 patients and validate the feasibility of using EBC for SARS-CoV-2 detection as a diagnostic test for the infection. Results showed that the need for mechanical ventilation was associated with higher viral load, while the need for oxygen administration or mechanical ventilation, less than 3 days since onset, and presence of cough or fever were significantly associated with higher detection rates.
