Abstract
There is provided an invention relating to methods of purifying atomic quantum clusters, in particular those consisting of 3 or fewer zero-valent metal atoms. The invention also relates to compositions and uses of such compositions, for the treatment of cell proliferative disorders.
Claims7
A composition purified by a process of purifying atomic quantum clusters (AQCs) consisting of 3 or fewer zero-valent transition metal atoms comprising:
- (i) applying a solution comprising a mixture of AQCs to a separation medium, wherein said separation medium either binds AQCs consisting of more than 3 zero-valent transition metal atoms, or binds AQCs consisting of 3 or fewer zero-valent transition metal atoms;
- and
- (ii) isolating AQCs consisting of 3 or fewer zero-valent transition metal atoms in solution,
- wherein said composition is free of AQCs consisting of more than 3 zero-valent transition metal atoms.
An aqueous composition consisting of atomic quantum clusters (AQCs) in aqueous solution, the AQCs consisting of 3 or fewer zero-valent transition metal atoms.
A composition consisting of atomic quantum clusters (AQCs) consisting of 3 or fewer zero-valent metal atoms, and free of AQCs consisting of 2 zero-valent transition metal atoms.
