Gecko-Inspired Nanotentacle Surface-Enhanced Raman Spectroscopy Substrate for Sampling and Reliable Detection of Pesticide Residues in Fruits and Vegetables

Abstract: Rapid sampling and multicomponent detection are crucial for monitoring of pesticide residues analysis. Here, a gecko-inspired nanotentacle surface-enhanced Raman spectroscopy (G-SERS) platform is proposed for the first time for the simultaneous detection of three kinds of pesticides via a simple and intuitive "press and peeled-off" approach. The G-SERS platform obtained from seeding deposition of silver nanoparticles (Ag NPs) on 3D PDMS nanotentacle array is flexible and free-standing. Compared with other subs… Show more

“…[105] Furthermore, Gecko SERS substrate based on PDMS as a platform using highly ordered anodic aluminium oxide (AAO) as a template and followed by depositing Au/Ag NPs on the platform with high density 'antenna' was prepared, and thiram (TMTD), methyl parathion (MPT), and malachite green (MG) on the surface of cucumber, apple and grape have been sampled and detected by a simple 'press and peel-off' method. [106] Recently, our team also developed a dual-function PDMS-sponge SERS substrate ( Figure 9). Not only the pesticides on the fruit surface, but also in the juice, were quickly detected on-site, due to the porous structure of the PDMS-sponge SERS substrate.…”

“…Simultaneous detection technology has been becoming a hot topic in analytical chemistry. Many methods have been reported for simultaneous detection of multi small molecular contaminants such as mycotoxins (Li et al, 2013(Li et al, , 2019Zhang et al, 2016;Wang et al, 2017a), pesticide residues (Bagheri et al, 2016;Wang et al, 2017b), and veterinary drugs (Taranova et al, 2015;Dasenaki et al, 2016;Zhu et al, 2016). Also, a lot of methods were described for simultaneous detection of multi microorganisms such as pathogenic bacteria (Li et al, 2015;Yoo et al, 2015;Vaisocherova-Lisalova et al, 2016), fungal pathogens (Playford et al, 2006;Priyanka et al, 2015;Rahn et al, 2016), and even varied pathogens that belong to different kingdoms (Leber et al, 2016).…”

“…Pesticides are widespread pollutants that can cause acute or chronic biological poisoning, so it is important to detect and control pesticide residues in food samples . However, the contents of pesticide residues in the samples are so low (as low as nanogram per kilogram), that the target pesticides are hard to determine in complex food substrate directly.…”
