Flexible surface-enhanced Raman scatting substrates: recent advances in their principles, design strategies, diversified material selections and applications

Carboxyl-functionalized two-dimensional MXene–Au nanocomposites were prepared as SERS substrates for the detection of melamine in dairy products

“…Due to its remarkable attributes, including high resolution, rapidity, ngerprinting capability, real-time analysis, and non-invasive nature, SERS stands as a prominent technique for qualitative and quantitative analysis of target analytes. [18][19][20][21][22] Consequently, we leverage SERS to achieve swi and highly sensitive detection of the target substance. Despite the many advantages of SERS technology, such as high sensitivity and rapid detection, its relatively weak signal has been criticized.…”

Surface-Enhanced Raman Scattering Coupled with In Situ Raman Spectroscopy for the Detection of the OER Mechanism: A Mini-Review

“…19,20 Precious metals such as Cu, Ag, Au, etc., and a few kinds of alkali metals with highly rough surfaces and certain structured morphologies are active toward SERS enhancement. 17,24 The SERS technique was first discovered Fleischmann et al at the Department of Chemistry at the University of Southampton, UK in the year 1973 from pyridine adsorbed on electrochemically roughened silver surface. 25 SERS is ideal for investigating intermediate species and reaction pathways in the OER process.…”

Place & Play SERS: sample collection and preparation-free surface-enhanced Raman spectroscopy

“…The ability to perform sensitive, real-time, in situ, multiplex chemical analysis is indispensable for diverse applications such as human health monitoring, food safety testing, forensic analysis, environmental sensing, and homeland security. [1][2][3][4][5] Surface-enhanced Raman spectroscopy (SERS), a method for signicantly enhancing inherently weak Raman scattering by localized surface plasmon resonance and measuring the enhanced Raman scattering signal for nondestructive structural analysis of samples, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] is an effective tool to provide the ability by virtue of its high sensitivity (even down to single molecules) and rapid label-free signal detection (down to ∼1 s or less) as well as the availability of portable Raman spectrometers (down to the passport size and 0.5 kg). [24][25][26] SERS is advantageous over other analytical methods such as mass spectrometry, gas chromatography, liquid chromatography, laser-induced breakdown spectroscopy, and uorescence detection because these methods require bulky and costly equipment, are timeconsuming in sample collection and preparation, or lack the capability of nondestructive, multiplex detection.…”
