Environmentally Friendly and Biodegradable Components for Biosensors

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.
