Coacervate Droplet Sequestration of Heterogenous Nanoplastics with Elastin-like Polypeptides
AI summary Read the abstract
Researchers provide raw microscopy images and supporting datasets for a study investigating how coacervate droplets formed from elastin-like polypeptides sequester heterogeneous nanoplastics, offering a biomolecular capture approach for nanoplastic removal.
This contains the source data - including raw, uncropped microscopy images corresponding to cropped images and the raw data corresponding to plots shown in the main text.

Coacervate Droplet Sequestration of Heterogeneous Nanoplastics With Elastin-Like Polypeptides.
AI summary Read the abstract
In a lab study, tiny plastic particles from PET, nylon, and polystyrene were tested with specially designed protein droplets. The droplets with oil-like (hydrophobic) surfaces attracted the plastic particles best, capturing over 80% of PET particles and continuing to capture plastic across repeated use cycles.
Coacervate Droplet Sequestration of Heterogeneous Nanoplastics With Elastin‐Like Polypeptides
AI summary Read the abstract
In lab tests, tiny plastic particles made from PET, nylon, and polystyrene were mixed with protein droplets designed to be either water-repelling or charged. The plastic particles stuck more to the water-repelling droplets, which captured over 80% of PET particles, and repeated use of the droplets captured over 70% of the PET across multiple rounds.
Coacervate droplet sequestration of heterogenous nanoplastics with elastin-like polypeptides
AI summary Read the abstract
Elastin-like polypeptide coacervate droplets selectively captured incidental nanoplastics of PET, nylon, and polystyrene with over 80% efficiency, driven primarily by hydrophobic surface interactions rather than exposed functional groups. This sequestration mechanism offers a promising biomimetic strategy for understanding and potentially removing environmentally relevant nanoplastics from aqueous systems.
Interfacial interactions between PMMA nanoplastics and a model globular protein: towards a molecular understanding of nanoplastic-driven biological dyshomeostasis
AI summary Read the abstract
Researchers investigated the molecular interactions between PMMA nanoplastics and a model globular protein to understand how nanoplastics disrupt normal protein function. They found that PMMA nanoplastics bind to and alter the structural conformation of the protein, potentially contributing to cellular protein dysfunction.
