Abstract
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.
Highlights
Detection of trace biological analytes and hazardous chemicals has become increasing important, since serious health risks and environmental problems can be mitigated or prevented by early detection
There are several conventional analytical techniques that have been utilized for the ultrasensitive detection of these analytes, some of which include high-performance liquid chromatography (HPLC) and gas chromatography-mass spectroscopy GC/MS [2], capillary electrochromatography (CE) [7], enzyme cycling assays [8], photoluminescence [9], and ion mobility spectrometry [10]

Summary
Detection of trace biological analytes and hazardous chemicals has become increasing important, since serious health risks and environmental problems can be mitigated or prevented by early detection. There are several conventional analytical techniques that have been utilized for the ultrasensitive detection of these analytes, some of which include high-performance liquid chromatography (HPLC) and gas chromatography-mass spectroscopy GC/MS [2], capillary electrochromatography (CE) [7], enzyme cycling assays [8], photoluminescence [9], and ion mobility spectrometry [10]. These techniques are time-consuming and require expensive equipment. Since its discovery in 1974 [11], the field of SERS has grown into an active area of research, including both experimental and theoretical studies [12], and has evolved from its fundamental understanding to promising applications [13]
