Is it possible to create an artifical selectively permeable membrane? I need one for a science fair project idea I had.

SUMMARY
Creating an artificial selectively permeable membrane is feasible, with dialysis filters serving as a prime example of such technology. Mechanical filters can be designed to selectively allow certain solutes to pass through, particularly when charged. However, achieving a membrane that selectively permits only sodium ions (Na+) is not currently possible, as membranes typically allow either positive or negative molecules to pass. For osmosis to occur, the membrane must be semi-permeable, which can be explored through various materials outlined in the linked Wikipedia article.
