Update: Deposition Enhancement via Thermophoresis

User Group Meeting 2018

Dr. Dirk Brogell

Federal Institute for Occupational Safety and Health (BAuA), Unit 4.5, 10317 Berlin, Germany

The poster demonstrates the particle deposition via thermal precipitation (particle precipitation by thermophoresis) on cells hosted at the air-liquid interface (ALI).
Advantages of thermophoresis
• Diffusion-like mechanism, gentle particle deposition 
• Independent from particle size (for nanoparticles)
• Homogenous deposition density profile 
• No need to manipulate aerosol properties for deposition (charge, size)

Characterization of a Vitrocell VC1 Using Nicotine Dosimetry: An Essential Component Towards Standardised In Vitro Aerosol Exposure of Tobacco and Next Generation Nicotine Delivery Products

IIVS at SOT 2018

1Institute for In Vitro Sciences, Inc., Gaithersburg, MD; and 2British American Tobacco, Southampton, United Kingdom.

This study demonstrates successful Vitrocell VC1 aerosol generation and delivery across multiple nicotine product categories (3R4F cigarette smoke, e-liquid and THP), as characterised using nicotine as a dosimetry marker. The data suggests the VC1 can reproducibly generate and deliver tobacco product and NGP aerosols for future in vitro assessment and matches the performance of reported exposure systems.
