Cell viability determined by MTT assay of reconstructed human epidermis after topical application for 42 h of short, long silver nanowire (AgNWs) and AgNO3 at 600 µg/mL and 3% Sodium dodecyl sulfate (SDS) as positive control of toxicity. Results are expressed as percentage of viability relative to the non-treated control samples as mean ± SD for n = 3. * p < 0.05 vs. control.

Viability (%)	Water	S-AgNW	L-AgNW	AgNO3	SDS
