Abstract
The present invention relates to a biopsy device, methods, kits and systems for marking the location of a biopsy site in order to later identify the location of a biopsy or surgery in a subject, where the marker is a dye or tattoo which is not visible to the naked eye under normal (white) light, but is visible under UV light. Some embodiments relate to marking a biopsy site for later visualization of the marker.
