Glossary

6 terms used across our articles and technical documentation, defined without jargon.

E

Encapsulation efficiency
The fraction of total payload that is successfully entrapped within the carrier rather than free in solution.
Enhanced permeability and retention (EPR)
The tendency of macromolecules and nanoparticles to accumulate in tumour tissue because of leaky vasculature and impaired lymphatic drainage.

L

Lipid nanoparticle (LNP)
A self-assembled vesicle of ionizable and helper lipids that encapsulates nucleic acid cargo for intracellular delivery.

P

Polydispersity index (PDI)
A dimensionless measure of particle size distribution width. Values below 0.1 indicate a monodisperse, reproducible formulation.

T

Transfection
The process of introducing nucleic acids into cells by non-viral means, typically with lipid, polymer or inorganic carriers.

Z

Zeta potential
The electrokinetic potential at a particle's slipping plane, used as a proxy for surface charge and colloidal stability.

Let's engineer the next delivery breakthrough together

We co-develop nanocarrier and biosensing programs with pharma, biotech and academic groups — from target selection through GMP supply.
