In health and environmental research, it is often necessary to quantify the concentrations of single (bio) nanoparticles present at very low concentrations. Suitable quantification approaches that rely on counting and tracking of single fluorescently labelled (bio) nanoparticles are often challenging since fluorophore self-quenching limits the maximum particle brightness. Here we study how the number of labels per nanoparticle influences the total brightness of fluorescently labelled cowpea chlorotic mottle virus (CCMV). We analyze i
