Advanced Nanoparticles sampling ON-THE-GO
What is Personal biodosimeter?
Airborne biological agents cause various infections,
and allergies, as well as create environment challenges
and meteorological phenomena. To help combat these
problems, Leti has introduced a portable, silent,
highly accurate and autonomous bioaerosol collector
with enhanced airborne pathogen sampling, including
bacteria or submicron viruses - a sensitivity lacking
in existing biodosimeters.
Particles are collected on a dry surface and then
concentrated in a small liquid medium. An analysis
can be performed leveraging a variety of techniques,
including but not limited to: culture, PCR, immunoassays,
mass spectrometry, and Raman spectroscopy.

What's new?
To develop a highly precise biodosimeter, Leti finely tuned the technology
and added a new approach:
- Low flow rate: to be representative of human exposure, the nominal
flowrate of the collector is similar to normal human breathing: 5 to 10 liters
per minute (LPM). This approach helps get a more compact, portable and
silent device, eliminating the need for heavy and noisy pumping systems
- Highly performance and accurancy: up to 98% accurancy for all particles
from 10nm to a few microns at 5 LPM
- Cell culture possible: keeps viability of some pathogens
- Silent, no mobile parts
- System fully compatible with sterilization by hydrogen peroxide
(other sterilization techniques can be further tested)
- Portable and standalone (battery powered
What's next?
The technology has been transferred to Bertin Technologies and will be
available on the market late 2018. Bertin Technologies already markets
the Coriolis® product line, offering a wide range of biocollection air samplers.
Leti technology will complement Bertin Technologies product range
with an ultraportable device capable of collecting a wide range of samples
from nanoparticles to microorganisms, and featuring enhanced accuracy
