The prevalent nature of micro and nanoplastics (MP/NPs) on environmental pollution and health-related issues has led to the development of various methods, usually based on Fourier-transform infrared (FTIR) and Raman spectroscopies, for their detection. Unfortunately, most of the developed techniques are laboratory-based with little focus on in situ detection of MPs. In this review, we aim to give an up-to-date report on the different optical measurement methods that have been exploited in the screening of MPs isolated from their natural environments, such as water. The progress and the potential of portable optical sensors for field studies of MPs are described, including remote sensing methods. We also propose other optical methods to be considered for the development of potential in situ integrated optical devices for continuous detection of MPs and NPs. Integrated optical solutions are especially necessary for the development of robust portable and in situ optical sensors for the quantitative detection and classification of water-based MPs.
微塑料和纳米塑料（MP/NPs）在环境污染及健康相关问题方面的普遍存在，促使人们开发了各种通常基于傅里叶变换红外（FTIR）和拉曼光谱的检测方法。不幸的是，大多数已开发的技术都基于实验室，很少关注微塑料的原位检测。在本综述中，我们旨在提供一份最新报告，介绍在筛选从自然环境（如水）中分离出的微塑料时所采用的不同光学测量方法。描述了用于微塑料现场研究的便携式光学传感器的进展和潜力，包括遥感方法。我们还提出了其他光学方法，以供考虑用于开发潜在的原位集成光学设备，以连续检测微塑料和纳米塑料。对于开发用于定量检测和分类水基微塑料的坚固便携式和原位光学传感器而言，集成光学解决方案尤为必要。
