Abstract:We used three dimensional cell cultures (3D) based on the magnetic levitation method (MLM) to evaluate cytotoxicity of photodynamic therapy (PDT). First, we decorated Hep G2 and MDA-MB-321 cells with NanoShuttle by introducing it in the media and incubated overnight. Next day, we transferred the cells to a 6-well plate and placed a magnetic driver on the top of the plate to start levitation. We monitored the formation of the 3D cell culture by optical microscopy and after four days, we added the photosensitize… Show more
