  Understanding the behavior of entities is critical to the development of new
policies and technologies aiming at global health and wellbeing; this paper
presents a unified model developed and validated for the deposition of
entities, ranging from a few Angstroms to tens of nanometers,on nanofibers. The
transport of entities is based on convective diffusion and interfacial
interactive diffusion. As the size of entities decreases to intermediate sizes
- between gas molecules and nanoparticles - adhesion probability on the surface
is less than unity, which is determined by the interfacial interactions and
kinetics of adhesion. Dimensionless surface coverage provides a better
understanding of adhesion kinetic by considering the effects of initial
concentration and time. The model is validated by available experimental data
in the literature.
