Microneedle for Enhancing IR detection of Microplastics using gold nanorods and specific peptides |
| 초록 |
The microplastic contamination of aquatic ecosystems has recently been reported to be a severe challenge to human society through many studies. Their negative impacts on the aquatic biota have been described to be fatal to living creatures particularly when their size are in nano-scale. In this study, we fabricated a microplastic specific detecting platform of microneedle for an enhancement of their detections through embedded with Au NRs, which were conjugated by PSBP having a strong selectivity toward PS microplastics. The PSBP was seven amino-acid oligo peptide and for the enhanced signal of chemical identification of microplastics, and FTIR detection method was mainly adopted accomplishing SEIRA phenomena by the Au NRs plasmonic antenna. Through the PSBP tethered Au NRs at the tip of the microneedle, specific binding of PS microplastics toward PSBP was confirmed by the amplification of FTIR peaks to determine whether PS was captured or not. |
