Concerns about surface area being a better determinant of nanoparticle toxicity than mass

Signal's description

(approx. 150 words)
Please describe the Weak Signal (approx. 150 words)
Some researchers suggest that biological activity of nanoparticles will depend on physico-chemical parameters not routinely considered in toxicity screening studies.

Overcoming sub-criticality and systemic failures
To be subcritical means that the effort in a particular field or subfield lacks resources, equipment or a sufficient number of researchers to achieve a desired goal
