Advances in Novel Nanomaterial-Based Optical Fiber Biosensors—A Review

“…In comparison to other nanostructures, 1D nanowires provide a number of benefits for molecular sensing that can be summed up as improved sensing capability, long-term stability, and reduced power consumption. The molecules attached to the surface of the nanowires induce changes in their characteristics because of the nanoscale diameter and high surface-volume ratio [ 123 ]. Numerous cutting-edge sensor designs have been established for the production of nanowire sensors and platform integration in order to address the rising need for multifunctional molecular detection and monitoring.…”

Multifunctional Wearable Device Based on an Antibacterial and Hydrophobic Silver Nanoparticles/Ti3C2Tx MXene/Thermoplastic Polyurethane Fibrous Membrane for Electromagnetic Shielding and Strain Sensing

“…Conductive nanomaterials, such as metal nanoparticles/wires, − carbon nanotubes (CNTs), , graphene, and transition metal carbide/carbonitride (MXene) sheets, , are typically used for construction of conductive networks. Silver nanoparticles (AgNPs), as classical conductive materials with high conductivity and nanoscale dimensions, have the potential to achieve excellent EMI shielding and human detection properties. ,, AgNPs are more conducive to reversible nanoscale recovery because AgNPs have a higher degree of freedom originating from the nanoparticle morphology compared with one-dimensional (1D) or two-dimensional (2D) nanomaterials with high aspect ratios .…”
