Fig. 2: Overview of the nanomaterial database.

a–h Distributions of nanomaterials accounting to a nanomaterial type, b surface ligand number, c nanomaterial size, d logP, e zeta potential, f cell viability, g reactive oxidative stress (ROS) and h cellular uptake. Nanomaterials in the database show chemical, structural, and biological diversity. The numbers in the brackets of b, c represent the range of the surface ligand number and nanomaterial size, respectively.
