Comparison of cellular viability in AuNP treated cells using Propidium Iodide (PI) uptake. Panels a and c shows the dot plot of Forward scatter (FSC)- CompPE-A::PE of normal cells (top panel) and cancer cells (bottom panel) in absence (left) and presence (right) of 100 μg/ml of AuNP treatment. In the dot plot, population are divided into four quadrants (Q1-Q4). Q3 is the PI negative or viable population and whereas Q2 and Q1 are PI positive or dead population of cells. Panels b and d showed effect of different dose of AuNP on viable or Q3 population in bar-graph representation. Viability of neither normal cells nor cancer cells was much affected by AuNP treatment.
