Nano(Q)SAR: Challenges, pitfalls and perspectives [PDF]

Nanotoxicology, 2014
Regulation for nanomaterials is urgently needed, and the drive to adopt an intelligent testing strategy is evident. Such a strategy will not only provide economic benefits but will also reduce moral and ethical concerns arising from animal testing. For regulatory purposes, such an approach is promoted by REACH, particularly the use of quantitative ...
