How to Eliminate Microplastics With Biological Nanoparticles
AI summary Read the abstract
Researchers propose using engineered pore-forming proteins—essentially biological nanoreactors—as a new approach to degrading plastic particles in the environment, leveraging protein engineering and AI-guided molecular modelling to design the system. This is an early-stage concept rather than a deployed technology, but it addresses the core challenge that no currently scalable solution exists for removing microplastics already dispersed in oceans, soils, and drinking water. If realized, this approach could complement filtration and chemical methods for microplastic remediation.
It is possible to recycle, although inefficiently, about 10% of the plastic we see, but there is still no sustainable solution to reduce plastic particle pollution found in oceans, soils, air, and drinking water. In this study, we explore how pore-forming toxins can be transformed into biological nanoreactors capable of degrading plastics, with the help of protein engineering driven by molecular modelling and artificial intelligence.

AI summary Read the abstract
This review evaluates bioengineering approaches to remove microplastics from the environment, including using microorganisms, plants, and engineered biological systems to break down or sequester plastic particles. While current biological methods are promising, the review identifies key limitations — including the challenge of targeting very small particles — that must be overcome for practical environmental cleanup.
Sub-micro- and nano-sized polyethylene terephthalate deconstruction with engineered protein nanopores
AI summary Read the abstract
Researchers engineered protein nanopores — tiny molecular tunnels — capable of breaking down nano-sized PET plastic (a common plastic found in bottles and packaging) under mild conditions. While these nanoreactors cannot degrade large plastic pieces, they show promise for filtering and destroying nanoplastics in wastewater treatment, where conventional methods fall short.
