Themed collection Soft Matter Underpinnings of Micro- and Nanoplastics
Materials science underpinnings of micro and nanoplastics
In this perspective, we discuss the fundamental mechanisms and the length scales responsible for the formation of micro- and nanoplastics (MNPLs), MNPL size, shape, and morphologies, their metrology, and open questions in the field.

Tire crumb in the environment: a review on occurrence, fate and recent advances in detection and analysis
This review provides a comprehensive overview of the characteristics of TWPs, their environmental occurrence, fate, and detection methodologies. The dominant methodological bottlenecks, key challenges, and possible way forwards are also discussed.

Mechanism of microplastic and nanoplastic emission from tire wear
Model experiments reveal that tire tread wears during driving to generate a population of aerosolized nanoparticles and larger microplastic particles. Formation of nano- and micro-particulate pollutants appear to arise from independent processes.

Tiny plastic, big trouble: how polystyrene nanoparticles impact DNA-damage repair deficient cervical cancer cells
Colloidal stability of micro- and nano-plastics influences interactions with human cells. These effects can be measured as a function of DNA damage repair via mitochondrial function, esterase activity, and oxidative stress.

About this collection
This collection, Guest Edited by Guruswamy Kumaraswamy (IIT Bombay), Sanat Kumar (Columbia University) and Tom McDonald (University of Manchester) focuses on mechanistic understanding of microplastic formation, transport processes relevant to microplastics in the environment, methods for preparation of realistic model microplastics for study, characterization of microplastics and interaction of microplastics with cells. The collection of review and research articles bridges interdisciplinary research in this field, exploring the soft matter underpinnings of microplastics and nanoplastics.
