An American college  student has developed a self-cleaning T-shirt that is impossible to stain, foreign media reported. Using "hydrophobic nanotechnology", the fabric of the garment consists of billions of silica particles. These cause water-based liquids - everything from sodas to ketchup to soy sauce - to simply roll off the material rather than soak into it. The Slilc T-shirt is being offered in black o white for $40.
