The presence of dissolved air and air in the free form (bubbles) was taken into account in the study of electromagnetic radiation on biological cells. It is shown that, upon movement in a temperature gradient field, some bubbles increase in size due to the dissolving of others and the coalescence of bubbles during collisions. As a result, the concentration of dissolved air decreases, which leads to cell responses. It is shown that the temperature gradient needed for substantial degassing can be generated by electromagnetic fields of low intensities.

Background: The unregulated use of pesticides by farmers, for crop productivity results in widespread contamination of organophosphates in real environmental samples, which is a growing societal concern about their potential health effects. The conventional approaches for the monitoring these organophosphate-based pesticides which include immunoassays, electrochemical methods, immunosensors, various chromatography techniques, along with some spectroscopic methods, are either costly, sophisticated, or involves the use of different metal complexes. Therefore, there is an urgent need for sensitive, quick, and easy-to-use detection techniques for the screening of widely used organophosphate-based pesticides.

Background: Nitroxyl (HNO) is an emerging signaling molecule that plays a significant regulatory role in various aspects of plant biology, including stress responses and developmental processes. However, understanding the precise actions of HNO in plants has been challenging due to the absence of highly sensitive and real-time in situ monitoring tools. Consequently, it is crucial to develop effective and accurate detection methods for HNO.

Background: Viral epidemics have long endangered human health and had dramatic impacts on environment and society. The currently known viruses and the rapid emergence of previously unknown viruses lead to an urgent need for effective virus detection strategies. It is important to develop methods that can detect multiple related viruses simultaneously in order to improve detection efficiency and to avoid treatment delays due to misdiagnoses.

Whilst the world sees the tremendous growth of mobile phone technology, radiofrequency electromagnetic radiation (RF-EMR) induced possible health effects have emerged as a topic of recent day debate. The current study is designed to test the hypothesis that chronic 900MHz radiation exposure would potentially dysregulate the stress response system (HPA axis) in vivo, via, its non-thermal mechanisms, leading to alterations in the microarchitecture of the adrenal gland, vulnerable brain regions such as the hippocampus which may results in altered behaviours in rats. Male albino Wistar rats aged four weeks, weighing 50-60g were subjected to 900MHz radiation from a cellphone for four weeks at a rate of one hour per day.

Electromagnetic radiation energy at millimeter wave frequencies, typically 30 GHz to 300 GHz, is ubiquitously used in society in devices for telecommunications; radar and imaging systems for vehicle collision avoidance, security screening, and medical equipment; scientific research tools for spectroscopy; industrial applications for non-destructive testing and precise measurement; and military and defense applications. Understanding the biological effects of this technology is essential. We have been investigating ocular responses and damage thresholds comparing various frequencies using rabbit eyes and dedicated experimental apparatus.
