“…On dilution, a less attenuated spectrum results in Figure eii, where further bands are evidenced permitting the baicalein/baicalain component to be more accurately observed, with the υ(C═O) attributed to the band at 1,623 cm −1 , the υ(OC) at 1,398 cm −1 , the out‐of‐plane bending at 733 cm −1 , ring υ(CC) at 1,623, 1,584, 1,365, and 1,337 cm −1 , and δ(HCC) at 1159 cm −1 . It is noted that the glycoside moiety of the latter flavone would be difficult to ascertain due to its very small Raman scattering cross section and its rather low affinity/binding with metal nanoparticles . Although the functional presence of the glycoside in baicalain would theoretically add solubility to the molecule in the colloidal solution over baicalein, this bulky group should be located far from the colloidal surface on absorption.…”

The identification of natural dyes in ancient textiles is a longstanding challenge for scientists; yet, the effort honours the skill and knowledge of master dyers by retracing traditional dyeing methods and assisting in conserving historical treasures for future generations. Here, the main constituents of selected native Japanese extracts from the roots of Lithospermum erythrorhizon and Scutellaria baicalensis, the barks of Phellodendron amurense and Morella rubra, the dried flower bud of Syzygium aromataticum, and the fruit of Terminalia chebula are determined by surface‐enhanced Raman spectroscopy following traditional Japanese extraction methods. The analytical amalgamation of data from SERS examinations on crude extracts and on subsequently refiltered and diluted extracts provides further effective and sensitive results for the combined identification of napthoquinones (shikonin and alkanin), alkaloid (berberine), polyhydroxyflavonoids (baicalin/baicalein, myricetin/myricitrin), diarylheptanoids, allylbenzene (eugenol), and tannins (gallic/ellagic acid). The comparison of results from this analytical protocol with those achieved by the more traditional chromatographic and mass spectrometric method provides and questions data regarding generally accepted marker components and enantioselective discriminations that serve to enrich the database of biological sources of colouring materials to be used in determining historically important Japanese colorants and dyestuffs.

“…The measurement of glucose in biological systems is key to monitoring and regulating the blood glucose level for both diabetes patients and healthy individuals. To detect glucose at very low levels, the label-free strategy [ 80 , 81 ] and the enzyme-mediated catalytic strategy [ 82 , 83 ] were mainly utilized in SERS methods.…”

“…For the label-free detection of glucose, a series of SERS-active substrates were designed. Sooraj et al [ 81 ] developed a coupled patterned Si with AgNPs arrays to improve the affinity of glucose with metal NPs. The limit of detection for glucose was low to 5 × 10 −5 g/mL, which was much lower than the blood glucose level.…”

Analyzing biomolecules is essential for disease diagnostics, food safety inspection, environmental monitoring and pharmaceutical development. Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for detecting biomolecules due to its high sensitivity, rapidness and specificity in identifying molecular structures. This review focuses on the SERS analysis of biomolecules originated from humans, animals, plants and microorganisms, combined with nanomaterials as SERS substrates and nanotags. Recent advances in SERS detection of target molecules were summarized with different detection strategies including label-free and label-mediated types. This comprehensive and critical summary of SERS analysis of biomolecules might help researchers from different scientific backgrounds spark new ideas and proposals.

“…Some process methods are used to make them arrange regularly [ 16 ]. When using Raman scattering to detect glucose, some researchers have used light analysis tubes, photonic crystal fiber, animals, and silver and gold as SERS substrates to detect glucose [ 17 , 18 , 19 , 20 , 21 ]. However, glucose cannot be easily adsorbed by precious metals.…”

Rapid Detection of Glucose on Nanostructured Gold Film Biosensor by Surface-Enhanced Raman Spectroscopy

In this report, we summarized our development of biosensors for Rhodamine 6G and in vitro glucose detection based on surface-enhanced Raman scattering technology. For the detection of both Rhodamine 6G and in vitro glucose, a nature-patterned substrate with gold films over nanostructures (NPS-AuFON) was used as the surface-enhanced Raman scattering sensor platform. The enhancement factor was calculated at . In the processing of the substrate, cyclic voltammetry was used to form nano-gold particles under different conditions. The Rhodamine 6G and glucose detection were then achieved on this substrate. Furthermore, we combined the potentiostatic technique and electrochemical adsorption to best detect glucose in low concentrations. The glucose oxidation potential (100 mV) was used to capture glucose close to the surface of the NPS-AuFON. The quantitative detection of glucose in solution and in situ inspection were confirmed. Further, we determined that this surface modification technology can reach the goal of experiments set by the World Health Organization to judge whether or not a patient is a diabetic by detecting a glucose concentration of 11.1 mmol/L (mg/dL) at a minimum.
