Special Issue Information

Dear Colleagues,

Nanomaterials have attracted widespread attention since the 1990s due to their distinct features that set them apart from bulk materials. Because of their novel optical properties and promising applications, the use of nanomaterials in the design of optical sensors is now one of the most active research fields. In the last decade, nanomaterials (graphene, carbon nanotubes, metallic nanoparticles, silicon nanowires, and quantum dots, among others) have been combined with modern optical sensing techniques to provide us with many new tools for sensing applications that are not accessible by traditional sensing techniques, such as surface-enhanced Raman spectroscopy (SERS), surface plasmon resonance (SPR), photonic crystals, optofluidics, etc. In order to promote further developments in these fields, we are delighted to invite you to contribute a paper and share your valuable work in our upcoming Special Issue, entitled “Applications of Nanomaterials in Optical Sensors, Second Edition”.

This Special Issue aims to cover recent advances and ongoing research in nanomaterial-based optical sensor applications. Full papers, communications, and reviews are welcome. Potential topics include, but are not limited to, the following:

  1. Optical sensors combined with nanomaterials (including optical fiber sensors, SPR sensors, planar waveguide sensors, laser-based sensors, biophotonic sensors, etc.);
  2. Novel surface-enhanced Raman spectroscopy (SERS) structures/devices and their applications in sensing;
  3. Photonic crystal sensors (including photonic crystal microcavities, photonic crystal fibers, bio-inspired and bio-enabled photonic crystals, metallic photonic crystals, etc.);
  4. Other new sensing mechanisms of nanomaterial-based optical sensors.

The integration of two-dimensional graphene with gold nanostructures has significantly advanced surface plasmon resonance (SPR)-based optical biosensors, due to graphene’s exceptional optical, electronic, and surface properties. This review examines recent developments in graphene-based hybrid nanomaterials designed to enhance SPR sensor performance. The synergistic combination of graphene and other functional materials enables superior plasmonic sensitivity, improves biomolecular interaction, and enhances signal transduction. Key focus areas include the fundamental principle of graphene-enhanced SPR, the functional advantages of graphene hybrid platforms, and their recent applications in detecting biomolecules, disease biomarkers, and pathogens. Finally, current limitations and potential future perspectives are discussed, highlighting the transformative potential of these hybrid nanomaterials in next-generation optical biosensing Full article
