The biophysicochemical interactions at the interfaces between nanoparticles and aquatic organisms: adsorption and...

Area of Science:

• Environmental Science
• Nanotechnology
• Aquatic Toxicology

Background:

• Nanoparticle (NP) toxicity in aquatic ecosystems is a growing concern.
• Nano-bio interfacial interactions are key to understanding NP biological effects.
• Research is needed to elucidate these interactions and their environmental implications.

Purpose of the Study:

• To review known nano-bio interactions in aquatic environments.
• To explore interfacial phenomena between NPs and aquatic organisms.
• To provide insights into the biological impacts of NPs.

Main Methods:

• Literature review of existing studies on nano-bio interactions.
• Description of fundamental interfaces and biophysicochemical interactions.
• Analysis of adsorption and internalization processes.

Main Results:

• Interfacial interactions are influenced by NP properties, suspending states, and environmental factors (pH, ionic strength, organic matter).
• Specific interactions were reviewed for microorganisms, hydrophytes, invertebrates, and fish.
• Analytical methods for investigating these interactions were summarized.

Conclusions:

• Nano-bio interfacial interactions significantly influence NP toxicity in aquatic organisms.
• Further investigation into these interactions is essential for environmental risk assessment.
• Future research should focus on elucidating these complex interactions and their consequences.
