virus A master engineer of nature, encapsulate and delivery genetic material With amazing precision. These natural systems have long been a source of inspiration for scientists seeking to revolutionize gene therapy. However, replicating the complex functions of the viral protein shell is capsid— that proved difficult. artificial nanocageAlthough it is modeled after a virus, it falls short due to its limited capacity and lack of complexity.
Now, this collaboration is Professor Lee Sang-min from Postec and 2024 Nobel Prize Laureate in Chemistry Professor David Baker from University of Washington has transformed the field. Their groundbreaking research nature December 18th, Used Artificial intelligence (AI) Mimics and enhances viral structures, providing new frontiers in therapeutic delivery.
The power of AI in redefining protein design
Traditional gene therapy vectors (such as: Adeno-associated virus (AAV)is limited by its small genetic payload capacity. To overcome this, the research team turned to: Computational design powered by AIwe revisit nanocages with tetrahedral, octahedral, and icosahedral shapes.
What stands out is that Icosahedral nanocageis 75 nanometers in diameter and has the ability to hold three times more genetic material than AAV. By incorporating subtle asymmetries found in natural viruses, these AI-designed nanostructures achieve levels of functionality previously unattainable using traditional methods.
Main features of Ai designed nanocage:
- Geometry: Tetrahedral, octahedral, icosahedral shapes.
- size: The maximum diameter is 75 nanometers.
- capacity: It holds three times more genetic material than traditional AAV.
- complicated: Contains six different protein-protein interfaces.
- accuracy: Symmetry was confirmed by electron microscopy.
Balancing precision and performance: testing the nanocage
AI-designed nanocages are not only efficient, but also innovative. Electron microscopy verified the accuracy of these designs, and functional experiments demonstrated the ability to deliver therapeutic genes directly to target cells. This combination of precision and performance redefines what is possible in medical biotechnology.
Potential uses:
- Gene therapy for genetic diseases.
- Development of next-generation vaccines.
- Precisely targeted drug delivery.
These multifunctional nanocages challenge the status quo and provide a breakthrough platform that goes beyond current limitations.
Collaboration at the forefront of innovation
This result highlights the value of interdisciplinary collaboration. professor leeI worked there for nearly three years. Professor Baker’s Having worked in the lab prior to joining POSTECH, he brings a unique perspective to this partnership. Supported by funding from. Korean Ministry of Science, Information and Communication and Howard Hughes Medical Institute (HHMI)this study exemplifies how global collaboration can foster scientific progress.

Rethinking the future of healthcare
“Advances in AI have opened the door to a new era in which we can design and assemble artificial proteins to meet human needs.” professor lee. These AI-designed nanocages represent a leap beyond imitation of nature and redefine nature. The potential goes far beyond gene therapy, and innovations are expected in the following areas: next generation vaccinetargeted drug delivery, etc.
This research is more than just a milestone;This is a bold statement that challenges conventional thinking. By harnessing the power of AI, scientists can not only learn from nature, but improve it, ushering in a new era of precision medicine. The question now is not whether AI can reshape biotechnology, but rather how far it will take us.
