March 20, 2026 - Modern devices, designed as portable and skin-integrated platforms, now provide biochemical sensing, electrophysiological signal monitoring, and continuous real-time insights into health status. In parallel, traditional diagnostic methods such as blood tests, imaging techniques (e.g., MRI and CT scans), and laboratory-based biochemical assays remain highly effective but are often time-consuming, costly, and require specialized infrastructure10,11. In contrast, smart biosensors, especially those enhanced through nanotechnology, offer significant advantages, including improved diagnostic sensitivity, faster response times and reduced costs, and scalable, low-cost mass production suitable for both clinical and point-of-care applications12,13.

February 16, 2026 - For instance, by taking advantage of nanotubes and nanosheets' large surface area, it is possible to perform analytical diagnostics with smaller volumes of samples, like a drop of blood, saliva, or sweat, subsequently making health monitoring less invasive and more accessible to the general public (Purohit et al., 2022). Due to their operation mechanism, electrochemical sensors are inherently suitable for miniaturization by integrating nanomaterials such as CNTs or graphene electrochemical biosensors can be fabricated into flexible substrates like wearable patches that can be applied to stick for continuous real-time monitoring through sweat for glucose or lactate with the readings transferred with the help of microcontroller through Bluetooth to a smart-phone providing the patient with direct access to their health related data (Shahid et al., 2023).

November 26, 2025 - Diabetes, a rapidly growing global health crisis, demands innovative diagnostic and monitoring tools for effective management and prevention of complications. Graphene-based glucose nanosensors have demonstrated exceptional sensitivity and physiological relevance, with detection limits as low as 0.0054 mg/dL and linear ranges extending from 0.18 to 900.78 mg/dL, well within the clinical glucose concentration range of 70–140 mg/dL in blood. To mitigate biofouling and maintain signal fidelity in complex biological matrices, several platforms employed Nafion and chitosan coatings, which preserved sensor stability for up to 48 h in serum.

In the domain of disease biomarker monitoring, Zhang et al. constructed a magnetic nanomechanical sensor (MNS) for the ultrasensitive detection of key cardiovascular disease (CVD) biomarkers—BNP, cTnI, and CK MB [105]. The device requires only a single drop of blood (<1 μL) and integrates a force–sensitive microcantilever with magnetic actuation to enable multi–target detection directly in blood without extensive sample pretreatment.

December 7, 2015 - We also discuss the incorporation of biorecognition elements into nanomaterial-based electrodes for immunosensing in unprocessed whole blood. ... Blood is one of the most significant sources of information for health and disease monitoring in the human body [1]. For example, monitoring the levels of biomarkers in the blood is known to be an effective method for early diagnosis of various diseases such as cancer, facilitating better treatment options and improved survival rates of patients [2]. Furthermore, therapeutic efficacy monitoring was demonstrated by following the levels of chosen biomarkers in blood before and after a therapy, which helps physicians determine the best treatment options [3]. Frequent monitoring of appropriate biomarkers is desirable as it provides fast and timely feedback.
