“…The LSPR shift induced by local changes in the refractive index or by coupling between particles above discussed are the simplest and more immediate approaches to exploit metal nanoparticles as active materials or transducers in chemical sensing but the evanescent near field surrounding metal nanoparticles can be also exploited to strongly amplify the optical signals (including, fluorescence, IR absorption, and Raman) of molecules which are located in close proximity to the particle's surface. These techniques, called Surface-Enhanced Fluorescence (SEF), (322,323) IR absorption (SEIRA) (324) and Raman spectroscopy (SERS),( 325) have shown great potential in the field of sensing and, in particular, SERS can allow increased sensitivity up to singlemolecule detection (326,327) but their working principles and their detailed description are far beyond the scope of this review.…”

In this work, novel types of nitrogen-doped carbon dots (N-CDs) were prepared from citric acid and glycine (GLY) as precursors through a simple pyrolysis method. The GLY-CDs showed strong fluorescence with a fluorescence quantum yield as high as 33.34% and good water solubility. The fluorescence of GLY-CDs could be selectively quenched by iron(III) ion (Fe 3+ ) resulting in the non-fluorescent complex. Due to the high affinity of Fe 3+ to adenosine-5 0 -triphosphate (ATP), the fluorescence of the GLY-CDs in GLY-CDs-Fe 3+ could be recovered by ATP. Thereby, quantitatively fluorescent turn-on detection of ATP could be achieved. The fluorescence recovery ratio was linearly proportional to the concentration of ATP with a detection limit as low as 15.0 nM, indicating the CDs have high sensitivity. The GLY-CDs were successfully employed in the detection of ATP in serum and cell lysates.

“…The sensor was fabricated using a composite of tungsten sulphide nanorod array on titanium mesh with DNA functionalised AuNPs (size = 18 ± 1 nm) as a sensor platform and a multiplexed signal amplifier in the form of a nanohybrid of AgNPs (lattice spacing = 0.27 nm) and zinc metal-organic framework nanozyme. Other geometries that have been widely explored in recent years for developing LSPR sensors include nanopyramids [95,104,105], nanourchins [106][107][108][109], nanocups [92,[110][111][112][113], nanoholes [114][115][116][117] and nanoislands [118][119][120][121][122].…”

In recent years, several types of optical sensors have been probed for their aptitude in healthcare biosensing, making their applications in biomedical diagnostics a rapidly evolving subject. Optical sensors show versatility amongst different receptor types and even permit the integration of different detection mechanisms. Such conjugated sensing platforms facilitate the exploitation of their neoteric synergistic characteristics for sensor fabrication. This paper covers nearly 250 research articles since 2016 representing the emerging interest in rapid, reproducible and ultrasensitive assays in clinical analysis. Therefore, we present an elaborate review of biomedical diagnostics with the help of optical sensors working on varied principles such as surface plasmon resonance, localised surface plasmon resonance, evanescent wave fluorescence, bioluminescence and several others. These sensors are capable of investigating toxins, proteins, pathogens, disease biomarkers and whole cells in varied sensing media ranging from water to buffer to more complex environments such as serum, blood or urine. Hence, the recent trends discussed in this review hold enormous potential for the widespread use of optical sensors in early-stage disease prediction and point-of-care testing devices.
