Abstract :The ongoing outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection throughout the world has revealed that simple, fast, low-cost, reliable and portable sensor systems should be developed immediately. Electrochemical and electrochemiluminescence (ECL) based pathogen sensors are promising alternative to conventional methods due to several advantages including in situ and fast response time, high sensitivity, low cost, being portable, easy-to operate and simple to construct. Carbon dots / graphene quantum dots have been used as labels, electrode material, ECL luminophores, electrode modification materials, amplifier, reaction catalysts to increase sensitivity and selectivity of electrochemical and ECL sensors. In this mini review, applications of carbon dots in electrochemical and ECL based sensors are summarized and the some examples of pathogen sensor are given.
