Raman Spectroscopy and Optical Tweezers for Precise Analysis and Assessment of Health Risks from Micro- and Nanoplastics

Microplastics pose a severe environmental problem, capable of crossing biological barriers such as the blood-brain barrier and potentially causing significant health risks. Raman spectroscopy, enhanced by the use of optical tweezers and hydrodynamic focusing, effectively identifies and quantifies micro- and nanoplastic particles under 1 µm. This method utilizes specialized microfluidic systems for precise manipulation and examination. Advances in measurement techniques enhance the accuracy of detection and signal integrity, providing a reliable basis for assessing health impacts. The precise positioning of particles through optical tweezers and control via hydrodynamic focusing allows for refined spectral analysis, crucial for understanding material composition and potential toxicity. This supports a well- founded analysis of the interactions of nanoplastics with biological systems and aids in the development of preventive measures. 138 hotonik
