Many studies of nanomaterials make non-systematic alterations of nanoparticle
physicochemical properties. Given the immense size of the property space for
nanomaterials, such approaches are not very useful in elucidating fundamental
relationships between inherent physicochemical properties of these materials and
their interactions with, and effects on, biological systems. Data driven
artificial intelligence methods such as machine learning algorithms have proven
highly effective in generating models with good predictivity and some degree of
interpretability. They can provide a viable method of reducing or eliminating
animal testing. However, careful experimental design with the modelling of the
results in mind is a proven and efficient way of exploring large materials
spaces. This approach, coupled with high speed automated experimental synthesis
and characterization technologies now appearing, is the fastest route to
developing models that regulatory bodies may find useful. We advocate greatly
increased focus on systematic modification of physicochemical properties of
nanoparticles combined with comprehensive biological evaluation and computational
analysis. This is essential to obtain better mechanistic understanding of
nano-bio interactions, and to derive quantitatively predictive and robust models
for the properties of nanomaterials that have useful domains of applicability.
