Optical biosensors are rapid, real-time, and portable, have a low detection limit and a high
sensitivity, and have a great potential for diagnosing various types of cancer. Optical …

Fiber‐optic technology emerged originally for applications in data transmission and
telecommunications. However, sensors based on fiber‐optics have been developed rapidly …

A new photonic crystal fiber (PCF)–based, hollow-core, optical waveguide is proposed and
numerically investigated to quickly identify numerous species of cancerous cells in the …

In this investigation, a “photonic crystal fiber (PCF)”-based “surface plasmon resonance
(SPR)” biosensor is proposed for the early detection of cancerous cells. The “finite element …

A novel design of metamaterial biosensor for cancer early detection is proposed and
analyzed. The suggested structure is based on two loops of hexagonal gold layers on a …

This paper proposes and demonstrates an ultrasensitive refractive index (RI) sensor based
on harmonic Vernier effect (HEV) and a cascaded Fabry–Perot interferometer (FPI). The …

A challenge for optical fiber biosensor is to achieve ultrahigh sensitivity with narrow full width
at half maximum (FWHM) of the spectrum. To address this challenge, an ultrahigh-sensitivity …

For early-stage cancer detection, a novel design of graphene-antimonene-coated uniform-
waist tapered fiber optic surface plasmon resonance (SPR) biosensor is demonstrated. The …

This paper contributes a novel design of sensor with a heart-shaped dual-core photonic
crystal fiber (PCF) to detect cancerous cells in human cervical, blood, adrenal glands, and …

Cancer is a major global health challenge, with many deaths due to uncontrolled tumor
cells. Traditional cancer diagnosis methods, such as physical examination and imaging …
