Over the past decade, electrochemical sensing for the purpose of building wearable point-of-need platforms has been widely investigated by researchers. These wearable platforms have the ability to non-invasively track biomarkers that are clinically relevant and provide a comprehensive evaluation of the user's health. Aptamer based sensing is gaining traction because of its significant advantages. They have properties like long-term stability, resistance to denaturation, and work sensitively. Using electrochemical sensing with aptamer based biorecognition is advantageous because it provides significant benefits like lower detection limits, wide range of operations, and most importantly, ability to detect using a label-free approach. This paper provides a review of the current state-of-the-art in the field of electrochemical aptasensing. This review looks at the significance of detection of biomarkers like glucose, cortisol etc. for the purpose of lifestyle and chronic disease monitoring. Moreover, this review will also provide a comprehensive evaluation of the current challenges and prospects for this field.
