In recent years, there has been significant interest in advanced nanobiosensor technologies with their exceptional properties for real-time monitoring, ultra-sensing, and rapid detection. With relevant experimental data, highly selective and hypersensitive detection of various analytes is possible using biosensors based on nanostructures. In particular, biosensors focus on vital issues such as disease early diagnosis and treatment, risk assessment of quality biomarkers, food-water quality control, and food safety. In the literature, there has been great attention to the preparation and sensing behavior of several nanomaterials-based sensors, such as polymer frameworks, metal-organic frameworks, one-dimensional (1D) nanomaterials, two-dimensional (2D) nanomaterials, and MXenes-based sensors. This chapter gives points to all aspects of fabrication, characterization, mechanisms, and applications of nanostructures-based biosensors. Finally, some smart advanced sensing systems for ultra-sensing nanoplatforms, as well as a comprehensive understanding of the sensor performances, current limitations, and future outlook of next-generation sensing materials, are highlighted.

Smart wearable electronic devices with superb sensing performance have aroused superb attention in recent years. However, designing an admirable strain sensor with the excellent balance between superior sensitivity and excellent stretchability remains a major challenge. Herein, we developed a conductive polydopamine-coated poly (ethylene terephthalate)/polyurethane fabric as the wearable strain sensor with the layered generating structure and the cooperative effect of carboxylated carbon nanotubes and reduced graphene oxide via self-assembly intercalation process. Obviously, the cooperative conductive effect of conductive fillers endowed the fabric with a superb integration of tunable strain sensitivity (0–265.48), outstanding electromechanical performance, great stretchability (0–220%), excellent heating performance, and long-term stability and repeatability under different strains over 2500 cycles. Especially, the as-prepared sensor was used for the detection of tiny body movements and vigorous human motions, indicating its further impressive prospect in wearable smart electronics. Therefore, such the proposed sensor with the layered generating structure exhibited remarkable potential for developing the flexible wearable electronic device of integrated sensing property and excellent electromechanical performance.

“…Meanwhile, the wettability of the electrode is a great obstacle to achieve stable, sensitive, and anti-corrosion strain sensors, so the application scenarios (rain, sweat, and swimming) of strain sensors require the electrode materials to possess superior water-resistance to maintain the stable electrical conductivity and to achieve high response sensitivity in varying hydrated conditions. , In order to reduce the infiltration of environmental water further, the hydrophobic polymers on the surface of conductive materials were considered as the protective layer .

Stretchable strain sensors have promising applications in flexible electronics field, such as artificial skin, health monitoring, and smart wearables. However, their anti-corrosion property, outstanding sensitivity, and environmental adaptability of strain sensors still remain a great challenge. Herein, a porous film was constructed by coating the stack of conductive fiber network with a 1H,1H,2H,2H-perfluorodecyltriethoxysilane array via molecular self-assembly, which formed a superhydrophobic surface on the conductive film. The conductive porous film demonstrated the superior water-resistance interface with a water contact angle of 179.5° and favorable conductive stability in humid environments. In addition, the film can also exhibit a strain sensitivity in the wide range of 0–100%, a rapid response of 150–200 ms, and excellent stability. Meanwhile, the superhydrophobic surface has made droplets easier to slip off its surface during stretching, and the fog also has rapidly coalesced into droplets on the film. The outstanding superhydrophobic surface was attributed to the stable sensing performance under the sweat condition, showing great potential in wearable sensors of stretchable, breathable, and water-resistant for human behavior monitoring.
