摘要：
目前环境中纳米塑料的范围只能通过可检测到的塑料废弃物进行外推估算。为了能够量化整个问题的程度，必须开发能够识别小于1 μm颗粒的检测方法。本文采用表面增强拉曼散射（SERS）对尺寸低至100 nm的单个纳米塑料颗粒进行成像和识别。我们在单个塑料颗粒上测量得到的实验增强因子超过三个数量级，而不是对浓度进行平均。我们的结果有助于更好地理解和应用SERS进行纳米颗粒检测，并为未来传感器的开发迈出了重要一步。
英文摘要：
Currently the extent of nanoplastic in the environment can only be estimated by extrapolation from the plastic waste that can be detected. To be able to quantify the whole extent of the problem, detection methods have to be developed that can also identify particles that are smaller than 1 $μ$m. Here we employ surface-enhanced Raman scattering (SERS) to image and identify single nanoplastic particles down to 100 nm in size. We obtain an experimental enhancement factor of more than three orders of magnitude measured on a single plastic particle instead of averaging over a concentration. Our results contribute to the better understanding and employment of SERS for nanoparticle detection and present an important step for the development of future sensors.
