Exploring the interactions between protein coronated CdSe quantum dots and nanoplastics
AI summary Read the abstract
Researchers investigated how protein coatings (coronas) that form on quantum dot nanoparticles affect their interactions with nanoplastics in the environment. These particle-particle interactions can alter how both quantum dots and nanoplastics behave, move, and accumulate in biological systems.
QDs after protein coronation can undergo sequential interaction with other pollutants which may alter the physiochemical property of the QDs and influence the stability of the corona proteins.

Coronas of micro/nano plastics: a key determinant in their risk assessments
AI summary Read the abstract
This review examines how micro- and nanoplastics develop surface coatings called coronas when they interact with biological and environmental substances. These corona layers, formed from proteins, organic matter, and other materials, can significantly change how plastic particles behave in the body and environment, affecting their uptake, distribution, and toxicity. The study suggests that understanding these surface coatings is essential for accurately assessing the real-world risks of plastic particle exposure.
Nanoplastics and Protein Corona - Investigating the Corona Structure and their Biological Impacts
AI summary Read the abstract
This PhD thesis investigated how proteins from biological fluids coat the surface of nanoplastics, forming a 'protein corona' that changes how nanoplastics interact with cells and tissues. The protein corona is important because it alters the biological behavior of nanoplastics once they enter the body, potentially affecting how harmful they are.
Role of the Protein Corona in the Colloidal Behavior of Microplastics

Researchers investigated how protein coronas form on polyethylene and polypropylene microplastics in biological media, finding that proteins act as surfactants that alter the colloidal behavior and stability of microplastics in aquatic environments.
Assessment on interactive prospectives of nanoplastics with plasma proteins and the toxicological impacts of virgin, coronated and environmentally released-nanoplastics
AI summary Read the abstract
Researchers found that nanoplastics quickly coat themselves in blood proteins, forming a multi-layered "corona" that changes the proteins' shape and makes them biologically harmful; these protein-coated nanoplastics caused more DNA and cell damage in human blood cells than bare nanoplastics. The study highlights the need to regulate nanoplastics in medical products and better understand how they accumulate in the body.
Strong binding between nanoplastic and bacterial proteins facilitates protein corona formation and reduces nanoplastics toxicity
AI summary Read the abstract
Researchers demonstrated that bacteria-derived proteins adsorb strongly onto nanoplastic surfaces to form a 'protein corona,' altering nanoplastic morphology and reducing their toxicity to bacterial cells — with the degree of protection varying by surface chemistry, as amino-modified nanoplastics showed the greatest reduction in oxidative damage after corona formation.
