Special Issue Information

Dear Colleagues,

Nanophotonics is a field of study that focuses on the interaction between light and nanoscale structures, typically at the scale of 1 to 100 nm. It involves the use of advanced technologies to manipulate and control light in nanoscale devices and structures, with the aim of creating novel applications and improving existing ones. Nanophotonics has the potential to revolutionize a wide range of fields, including telecommunications, sensing, energy harvesting, and biomedical imaging. By manipulating light at the nanoscale, researchers can create materials with unique optical properties, design devices with high efficiency and sensitivity, and develop new methods for detecting and manipulating biological molecules. Some of the key areas of research in nanophotonics include plasmonics, which involves the interaction of light with metallic nanoparticles; metamaterials, which are artificial materials with unique optical properties; and quantum optics, which explores the behavior of light at the quantum level.

This Special Issue invites manuscripts that report on the recent advances in nanophotonic devices. Theoretical, numerical, and experimental studies are welcome on topics including, but not limited to, the following:

  • Optical micro/nano-sensors and systems;
  • Nanophotonics for sensing and biosensing applications;
  • Nanophotonics for optoelectronics and data communication;
  • Neuromorphic circuits and photonic artificial intelligence;
  • Plasmonic nanoparticles and their applications;
  • Metamaterials for manipulating light at the nanoscale;
  • Quantum dots for photonics applications;
  • Nanoscale photonic crystals and their properties;
  • Nanoscale waveguides for integrated photonics;
  • Nanostructured surfaces for light trapping and enhanced absorption;
  • Ultrafast optical phenomena in nanoscale materials;
  • Active nanophotonics and their applications in energy harvesting;
  • Nonlinear nanophotonics for ultrafast all-optical switching;
  • Integrated nanophotonic circuits for quantum information processing;
  • Optical antennas for enhanced light–matter interactions;
  • Nanophotonic devices and systems for energy conversion, etc.

This article describes a novel electrochemical on-chip biosensor that utilises the anti-PSA antibody (Ab) and silver nanoparticles (AgNPs) to enhance the sensing and detection capability of the prostate-specific antigen (PSA) in the blood. The AgNPs are prepared, characterised, and applied to a silicon photonic on-chip biosensing receptor platform designed to enhance the accurate detection of PSA. The AgNPs were synthesised by a chemical reduction method using silver nitrate (AgNO3) as the precursor. Transmission electron microscopy (TEM), selected area electron diffraction (SAED), energy dispersion X-ray spectroscopy (EDS), small angle X-ray scattering (SAXS), X-ray diffraction (XRD), and light microscopy were among the methods used in the characterisation and analysis of the AgNPs. Each stage of the immunosensor fabrication was characterised using cyclic voltammetry. The proposed immunosensor was applied in the detection of PSA, a prostate cancer biomarker, with a high sensitivity and a limit of detection of 0.17 ng/mL over a linear concentration range of 2.5 to 11.0 ng/mL. The immunosensor displayed good stability and was selective in the presence of interfering species like immunoglobulin (Ig) in human serum, ascorbic acid (AA), and diclofenac (Dic). The detectivity and sensitivity are significantly higher than previous reports on similar or related technologies. Full article
