Optical photothermal infrared spectroscopic assessment of microplastics in tissue models and non-digested human tissue sections

AHAzita HassanMazandaraniJMJohn M. MastersonWQWilliam Querido

Key Points

  • The research aims to develop a method for detecting microplastics in human tissue without using harsh digestion techniques.
  • Utilized optical photothermal infrared spectroscopy (O-PTIR)
  • Assessed non-digested human tissue and tissue phantom sections
  • Maintained spatial context and chemical specificity
  • Successfully detected microplastics in tissue samples
  • Eliminated the need for aggressive digestion protocols
  • Provided spatially specific identification of contaminants

Abstract

A novel O-PTIR method detects and identifies microplastics directly in non-digested human tissue and tissue phantom sections, preserving spatial context and chemical specificity—eliminating the need for harsh digestion protocols.
