Criterion for the intracellular delivery score (IDS) to find optimal treatment conditions.

Criterion for the intracellular delivery score (IDS) which was categorized, and calculated by the interaction of the delivery efficiency (D), cell membrane permeability (P), and cell viability (V) after 4 and 20 hours of treatment.
