Environmentally Friendly and Biodegradable Components for Biosensors

Abstract

The pandemic of coronavirus diseases 2019 (COVID-19) attracts dramatic attention worldwide that biosensing technology plays an essential role in screening, tracing, and diagnostics of the diseases in society. The World Health Organization (WHO) recommends the significant features of biosensor development, called ASSURED: affordable, sensitive, specific, user-friendly, rapid and robust, equipment-free, and delivered to the end-user. Consequently, the practical, low-cost, and environmentally friendly components of biosensors are urgently required in the future for such cases of massive tests in homecare and point of care. This article reviews the emerging trend and applications of recent biosensor research utilizing reusable and biodegradable components. The challenges of future development were discussed to overview the consideration of the subsequent research roadmap.

Challenges and Advances of Hydrogel-Based Wearable Electrochemical Biosensors for Real-Time Monitoring of Biofluids: From Lab to Market. A Review

“…The replacement frequency depends on the type of device and targeted application . Nowadays there are concerns about the impact of biosensor disposal on the environment. , Therefore, it is important to minimize the environmental impact of wearable biosensors, for example, by developing sustainable alternatives that can be reused or recycled. In a study, a highly flexible hydrogel-based electrochemical sensor was recently developed for the reliable and ultrasensitive detection of H 2 O 2 in liquid environments.…”

Tesla Valve Microfluidics: The Rise of Forgotten Technology

“…Another advantage of passive components is their smaller footprint, making them suitable for micro-scale devices. These components also have a simple control operation, which can help reduce complexity in microfluidic systems [20,21]. TVs have been studied for their use as passive components in microfluidics because of their straightforward design and effective fluidic control.…”

“…The world health organization (WHO) defined the requirement of biosensor to be AS-SURED: affordable, sensitive, specific, user-friendly, rapid and robust, equipment-free, and deliverable to end users [21]. As passive components rely with the design, topology without moving part, TV based channel will be compatible with the aspect of affordability because of the low-cost fabrication, robustness, and equipment free to control the valves because there is no actuators.…”
