LightWeigh: characterize your nanoparticles in minutes

A compact, label-free instrument that measures the concentration, size and mass of your 20 – 300nm particles at single-particle level — AAV, LV, LNP, EV and more.

LightWeigh nanoparticle characterization instrument

Half a day
of training

Compact:
45x60cm

Patented

As simple as load, press, read

Pipette 10µL of your sample, press start, and read your results — no labelling, no calibration, and no settings to change between particle types. A measurement takes 3 – 10 minutes, and training takes less than half a day.

Empty/full capsid ratio

AAV empty full capsid separation by mass
Example of full/empty measurement by DH-NTA

Quantify the empty, partial and full capsid ratio of your viral and non-viral  vectors — and the concentration of each population — at single-particle level. A critical quality attribute for gene therapy, measured in minutes on 10 µL.

Yield control

Get an absolute particle concentration to track and optimize your production yield, label-free and standard-free — robust across dilutions from 1×10⁸ to 1×10¹⁰ particles/mL

Aggregation control

AAV measurements with dimers and trimers measured by LightWeigh

Detect aggregates and distinct sub-populations early in your process — across viral vectors, LNPs and extracellular vesicles — that bulk methods average out.

Validated across particle types

Our instrument is agnostic to the type of nanoparticles. It works with  any type of biological 20-300nm nanoparticles and also on other non-biological nanoparticles such as gold nanoparticles (down to 10nm) and silica nanoparticles.
