A nano-scale filter ( 10 ) includes a porous supporting component ( 14 ) and a carbon nanotube filtration membrane ( 12 ) sintered on a top surface of the porous supporting component. The porous supporting component has a number of micro-scale pores. The filtration membrane is configured as a network formed by aggregating a number of multi-junction carbon nanotubes. The multi-function carbon nanotubes are selected from the group consisting of two-dimensional junction carbon nanotubes ( 30, 40, 50, 60 ), three-dimensional junction carbon nanotubes ( 20 ) and an admixture thereof. A method for making the nano-scale filter is also provided.
