About

Phoreus Biotechnology is an early-stage biotechnology company specializing in drug delivery innovation through its proprietary Peptide Nanoparticle (PNP) platform. Based in Olathe, Kansas, the company develops self-assembling nanostructures designed to overcome the stability, targeting, and manufacturing limitations of traditional delivery systems for therapeutics. Phoreus focuses on applications such as mRNA vaccines and genetic treatments, aiming to improve therapeutic efficacy and eliminate costly storage requirements.

The company's core advantage lies in its Peptide Nanoparticle (PNP) technology, which offers a stable, non-toxic, and highly targetable alternative to conventional lipid-based carriers. This platform eliminates the need for cold-chain storage for sensitive biologics, reduces immune responses, and supports multiple administration routes, addressing key challenges in therapeutic development.
