High order image correlation spectroscopy of plasmon-coupled gold nanospheres for their cellular uptake study

High order image correlation spectroscopy is a non-destructive technique which enables one to calculate the gold nanosphere uptake inside a cell. Usually it is difficult to count the gold nanosphere uptake as it has a property called plasmon-coupling. But the high order image correlation spectroscopy helps to overcome this problem. The study can have application in the field of drug delivery where one is concerned about the amount of drug to be delivered to a particular location.
