Gold (Au) has been widely used as a material for Surface Enhanced Raman Spectroscopy (SERS) due to its plasmonic properties, stability and biocompatibility. Conventionally for SERS application, Au is deposited on a rigid substrate such as glass or silicon. The rigid substrates severely limit analyte collection efficiency as well as portability. Here, flexible substrates like carbon cloth and carbon paper were investigated as potential substrate candidates for SERS application. The flexible substrates were coated with Au nanostructures by electrodeposition. Model analyte, Rhodamine 6G was utilized to demonstrate the capabilities of the flexible SERS substrates. Additionally, the pesticide paraoxon was also detected on the flexible SERS substrates as well as on a real sample like the apple fruit.

“…Especially, in recent years, the SERS systems constructed from soft/flexible materials have drawn increasing attentions owing to their distinct merits for real‐time point‐of‐care (POC) diagnostics. Currently, the flexible SERS platforms are primarily classified into i) actively tunable SERS, ii) swab‐sampling strategy as well as iii) in situ SERS monitoring means . Among them, the in situ SERS detection based on the flexible substrates is considered as the most promising approach, which is performed by first conformally attaching the flexible SERS substrates onto objective surfaces of interest, followed by the excitation of incident photons and collection of Raman signals from the back side of the SERS substrates.…”

Skin‐inspired wearable devices hold great potentials in the next generation of smart portable electronics owing to their intriguing applications in healthcare monitoring, soft robotics, artificial intelligence, and human–machine interfaces. Despite tremendous research efforts dedicated to judiciously tailoring wearable devices in terms of their thickness, portability, flexibility, bendability as well as stretchability, the emerging Internet of Things demand the skin‐interfaced flexible systems to be endowed with additional functionalities with the capability of mimicking skin‐like perception and beyond. This review covers and highlights the latest advances of burgeoning multifunctional wearable electronics, primarily including versatile multimodal sensor systems, self‐healing material‐based devices, and self‐powered flexible sensors. To render the penetration of human‐interactive devices into global markets and households, economical manufacturing techniques are crucial to achieve large‐scale flexible systems with high‐throughput capability. The booming innovations in this research field will push the scientific community forward and benefit human beings in the near future.

“…[111] In our previous study, a cotton swab (cotton Q-tip) loaded with Ag NPs was prepared and employed to detect traces of explosives on fingers. [112] In addition, the cotton swab was also prepared as a flexible SERS substrate for the simple and rapid detection of carbaryl residue on the surface of cucumber (with an irregular surface), [113] which accelerated the transformation of this SERS technique into a practical analytical tool.…”

On‐site identification and quantification of chemicals is critical for promoting food safety, human health, homeland security risk assessment, and disease diagnosis. Surface‐enhanced Raman spectroscopy (SERS) has been widely considered as a promising method for on‐site analysis due to the advantages of nondestructive, abundant molecular information, and outstanding sensitivity. However, SERS for on‐site application has been restricted not only by the cost, performance, and portability of portable Raman instruments, but also by the sampling ability and signal enhancing performance of the SERS substrates. In recent years, the performance of SERS for on‐site analysis has been improved through portable Raman instruments, SERS substrates, and other combined technologies. In this review, popular commercial portable Raman spectrometers and the related technologies for on‐site analysis are compared. In addition, different types of SERS substrates for on‐site application are summarized. SERS combined with other technologies, such as electrochemical and microfluidics are also presented. The future perspective of SERS for on‐site analysis is also discussed.
