I suggest everyone to re-read the announcement especially the bits below, its quite significant what they have got so far IMO backed by Hudson Institute !!

PhotosoftTM caused efficient and highly effective cancer cell destruction in vitro, with 100% cell death achieved in a matter of minutes following light activation.

In the absence of light activation, PhotosoftTM was completely non-toxic to cells – highlighting its potential for clinical application without inducing non-specific phototoxicity, a major impediment experienced in the clinical application of other photosensitiser compounds.

Photodynamic Therapy (PDT), combining a photo-sensitising compound and light to generate destructive reactive oxygen species, is an effective strategy for tumour tissue ablation. The efficiency of a photosensitiser is one of the main factors for determining its feasibility as a Photodynamic Therapy. Whilst several photosensitisers are clinically approved, some have undesirable properties including extreme photosensitivity, poor water solubility and inadequate selectivity, limiting their clinical application.
