“…Vacuum‐assisted filtration owns the advantages of simplicity and convenience, which is widely used in the preparation of cellulose film‐based flexible SERS substrates. [ 41–46 ] Besides, the pen‐writing technique is also a universal method for noble metal nanostructures deposition on cellulose film. Taking silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) as inks, the flexible and tunable SERS sensing platforms can be fabricated.…”

Flexible surface‐enhanced Raman scattering (SERS) substrates have recently attracted growing research interests in real‐world applications due to their unique advantage of sensitivity and flexibility. Reviewing the latest progress of flexible SERS substrates is very important for further development of high‐quality detection platforms. Herein, the recent developments of flexible SERS substrates in fabrications and applications are introduced. First, three categories of current flexible SERS platforms including paper‐based SERS substrates, polymer‐based SERS substrates, and inorganic materials‐based SERS substrates are demonstrated in depth. Then, the focus is moved to the applications of flexible SERS substrates. Combining swab strategies, lateral flow strips, paper‐based microfluidics, and in situ detection techniques, flexible SERS platforms provide intriguing applications in various fields. The challenges are also identified for practical applications on account of substrates’ uniformity, quantitative accuracy, multiplex detection ability, and overall cost. It is believed this review will be of help for researchers to design and fabricate flexible SERS substrates with higher performance and lower cost, and finally realize the practical applications.

“…The prominent peaks centered at 1003, 1078, 1178 and 1581 cm À1 , were consistent with the Raman spectra of 4-ATP molecules reported in the literature. 40,41 The SERS signal intensity of the substrates prepared without electroless plating was the lowest, because only sparse Au NPs were adsorbed onto the surface of the lter paper. It was ultimately noted that the intensity of the SERS signal for 4-ATP gradually increased along with the increase in the electroless plating time, and reached a maximum at 40 minutes and then declined with prolonging of the electroless plating time.…”

“…To prepare that kind of SERS substrate, many approaches are taken under consideration, including the use of polymer nanofabric [35,36], cellulose [37,38], or flexible piezoelectric-modulated layer [39] decorated by silver or gold nanoparticles or nanowires. Few of these substrates can find its application in food industry, especially for pesticide detection [37,38,40], and others in explosive materials detection [41]. Despite many unquestionable advantages, such as high sensitivity, that kind of substrates can be temperature and humidity sensitive as well as still has short lifetime.…”

Surface-enhanced Raman spectroscopy (SERS) is an analytical technique, which allows to identify traces of chemical or biological substances in many field, like pharmaceutical and food industries, homeland security, nanosensors, or environmental protection. The analytes are identified based on their vibrational spectra, unique for a given compound. The advantage of SERS is effective qualitative analysis of trace amounts of analyte, but the disadvantages are stability of substrate and repeatability of measurements. The challenge is to improve SERS substrates to minimize these drawbacks. Nowadays high-precision electron beam lithography or focused ion beam is used in SERS substrate fabrication, which is impractical for large-scale production. In recent years, researchers' attention has focused on porous anodic oxides, with inexpensive and scalable production method, as potential materials for SERS substrates. This chapter will discuss the progress of anodic oxides used as a SERS substrate, and the brief description of conventional SERS substrate fabrication methods will be presented.
