Affinity Sensors for the Diagnosis of COVID-19

2021

The coronavirus disease 2019 (COVID-19) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was proclaimed a global pandemic in March 2020. Reducing the dissemination rate, in particular by tracking the infected people and their contacts, is the main instrument against infection spreading. Therefore, the creation and implementation of fast, reliable and responsive methods suitable for the diagnosis of COVID-19 are required. These needs can be fulfilled using affinity sensors, which differ in applied detection methods and markers that are generating analytical signals. Recently, nucleic acid hybridization, antigen-antibody interaction, and change of reactive oxyge…

Nanomedicine: A Diagnostic and Therapeutic Approach to COVID-19

2021

The SARS-CoV-2 virus is causing devastating morbidity and mortality worldwide. Nanomedicine approaches have a high potential to enhance conventional diagnostics, drugs and vaccines. In fact, lipid nanoparticle/mRNA vaccines are already widely used to protect from COVID-19. In this review, we present an overview of the taxonomy, structure, variants of concern, epidemiology, pathophysiology and detection methods of SARS-CoV-2. The efforts of repurposing, tailoring, and adapting pre-existing medications to battle COVID-19 and the state of vaccine developments are presented. Next, we discuss the broad concepts and limitations of how nanomedicine could address the COVID-19 threat. Nanomaterials …

Biosensors for the determination of SARS-CoV-2 virus and diagnosis of COVID-19 infection

2022

Monitoring and tracking infection is required in order to reduce the spread of the coronavirus disease 2019 (COVID-19), induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To achieve this goal, the development and deployment of quick, accurate, and sensitive diagnostic methods are necessary. The determination of the SARS-CoV-2 virus is performed by biosensing devices, which vary according to detection methods and the biomarkers which are inducing/providing an analytical signal. RNA hybridisation, antigen-antibody affinity interaction, and a variety of other biological reactions are commonly used to generate analytical signals that can be precisely detected using electro…

Evaluation of anxiety, depression, aggression, and life satisfaction of nurses working with severe acute respiratory syndrome coronavirus 2-infected …

2023

Background: Negative emotions such as anxiety, depression, and aggression are among the factors that influence the level of perceived life satisfaction. Life satisfaction is related to physical and mental health and is an important component of human functioning. Nurses are particularly vulnerable to negative emotions due to their high-risk occupation and contact with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals. Aim of the study: The main objective of this study was to investigate the relationship between life satisfaction and levels of anxiety, depression, and aggression among nurses working with patients infected with the SARS-CoV-2 virus. Material an…
