Abstract:
1. A method for detecting afferent lymph vessel inflow regions, the method comprising: injecting a predetermined amount of 15-20 nm quantum dots into a patient; detecting a fluorescence of the quantum dots in a sentinel lymph node of the patient; extirpating the sentinel lymph node; measuring a fluorescence intensity of the quantum dots for each of a plurality of regions in the extirpated sentinel lymph node using a sinqie-molecule confocal fluorescence microscope; and detecting from the plurality of regions of the extirpated sentinel lymph node, a higher quantum dot fluorescence intensity than other regions of the extirpated. sentinel lymph node, wherein the regions having significantly hit. her quantum dot fluorescence intensity in the extirpated sentinel lymph node provides detection of the afferent lymph node vessel inflow regions.
