Hybrid Semiconductor Photocatalyst Nanomaterials for Electrochemical Sensing Applications

HybridHybrid Semiconductor Nanomaterials semiconductor photocatalyst nanomaterialsSemiconductor photocatalyst Nanomaterials (HSPNs)HSPNs, an emergingSensing applications class of two dimensional (2D) layered materials finds diverse application in medical and environmentalEnvironmental Applications, industrial applications. Some of the inorganic semiconductors such as ZnO, TiO2, WO3, NiS, CoS, MoS2MoS and CdSCdS are the key factors amongElectrochemical Sensing semiconductors with its respective bandgap responsible for detection mechanism. Electrode modification is a crucial part of the sensorSensors as it is the sole deciding factor for high selectivity, sensitivity, reproducibility, dynamic ranges and ultrasensitive detection limits of sensing devices. In present chapter, the synthetic routes, and fabrication strategies of HSPNsHSPNs are discussed with a focus on the synergistic effect of HSPNs in combination with redox mediators and metal nanoparticles, metal oxidesMetal Oxides, fluorophores or biomolecules. HSPNsHSPNs also serve as an efficient modifier with carbon systems and their wide exploration of electrochemical detection of reactive oxygen species (ROS), hydrogen peroxide, superoxide, amino acids, hydrazine, glucose, neurotransmitters, pharmaceutical drugs, pesticidePesticides etc., have been discussed in detail in this chapter. Additionally, the HSPNs based miniaturized electrochemical sensorsSensors for various crucial analytes have been elaborated. Finally, we conclude the summary, challenges encountered in this filed with possible remedies and future scope of HSPNsHSPNs in wearable sensorsSensors and electronics.
