# nCage Therapeutics > nCage Therapeutics builds TRAP-cages: synthetic virus-like particles that display antigens on their surface and open on command to release cargo inside the cell. nCage Therapeutics is a biotechnology company established in 2019, based in Kraków, Poland, with operations at NETPark in the United Kingdom. Its TRAP-cage platform builds synthetic virus-like particles from rings of the bacterial TRAP protein, held together by gold(I) ions. The cages carry no genetic material, display antigens on their surface, and — uniquely — open on command inside the cell to release cargo loaded in their interior.

That single property is what makes it a delivery system rather than another nanoparticle. - [Best-in-class vaccines, built on one platform](https://www.ncage.org/md/en/pipeline): nCage is developing a series of vaccines using the TRAP-cage synthetic VLP platform. - [News](https://www.ncage.org/md/en/news): Announcements, collaborations and results from nCage Therapeutics - [Presentations](https://www.ncage.org/md/en/presentations): Conference decks and introductory material, ready for download. - [Posters](https://www.ncage.org/md/en/posters): Scientific posters presented at conferences, ready for download. - [Talk to the people who build the cage](https://www.ncage.org/md/en/contact): Ask about the technology, explore a collaboration, or send us a question.
