Amperometric biosensors have emerged as a cutting-edge technology in clinical diagnostics, thanks to their high level of sensitivity, rapid analytical results, compact size, and ability to monitor health parameters non-invasively and continuously using flexible and wearable sensors. This review explores the latest developments in the field of amperometric biosensing for medical applications. It discusses the materials used to construct these sensors and pays particular attention to biosensors designed to measure glucose, lactate, cholesterol, urea, and uric acid levels. The review also addresses the technological limitations and drawbacks of these devices. Furthermore, it presents the current status and identifies future trends in the development of flexible, wearable biosensors capable of providing continuous monitoring of a patient's health status.

Over the past few years, photocatalytic methods have shown great promise as low-cost, environmentally friendly, and sustainable technologies. During the development of photochemistry, a variety of sources of light were used, including sunlight, compact fluorescent lamps, lasers, and even light-emitting diodes. As a part of preparing diverse organic compounds, the photochemical approach was used, for instance, to form rings, arylated compounds, cycloaddition, functionalized compounds, dehalogenated compounds, oxidized compounds, reduced compounds, isomers, and sensitized compounds. Solar energy is a renewable resource that can be harvested from the sun and this light energy can be changed into chemical energy with the help of photocatalysts. During this green approach, electron-hole pairs are generated in photocatalysts in order to begin reactions by using solar light. It has been highlighted in this article that there have been impressive developments in the use of light, mainly the solar light, to promote important organic reactions, which would otherwise be unattainable under thermal conditions.

Bis(indolyl)Methanes are a major class of heterocycles with considerable promise for technological and biological applications and being fluorescent active as well. Considering the extensive quantity of work on various synthetic techniques, the objective of this study is to measure the previous and current status of research studies related to different types of Bis(indolyl)methane (BIM) derivatives. Currently, research is focused on developing green synthetic strategies for dependable, sustainable and environmentally friendly synthetic processes. The present literature describes the formation of BIM moieties starting from suitable precursors using conventional reaction procedures, as well as reactions mediated by microwaves, ultrasounds, organocatalysts, transition metal catalysts, metal-free ionic liquid catalysts, and other environmentally friendly reaction protocols. The current review discusses the explosive development of different environmentally friendly synthesis routes for bis(indolyl)methane and its analogues during the past few decades. Moreover, this study includes the biological activities such as antibacterial, anti-cancer, anti-inflammatory, etc., of BIM derivatives, which have been investigated in recent years.
