“…With the development of flexible and wearable electronics, smart textiles have been used in various sensors. 11,12 Till now, researchers have developed SERS sensors based on textiles by employing various fabrication methods including dyeing-like method, 13 self-assembling, 14,15 in situ growing, 16,17 and electrospinning. 18,19 Though these methods can produce fine nanoscale patterns, they still have some insufficiencies in terms of time consumption and require a lot of labours for large batch fabrication, which are essential for the practical application in on-site analysis.…”
