Abstract
Modified surfaces of the present disclosure include a surface or substrate material, a magnetic field, which may be generated through the use of a magnet placed at a distance beneath the surface or substrate, or placed above the surface or substrate, or through the use of a magnetic surface or substrate, and a magnetic fluid, such as ferrofluid or ferrogel, deposited in a layer on the top of the surface or substrate. The modified surfaces may be icephobic. In addition, a droplet of liquid placed on the modified surface can be manipulated through placement of a local heat source in proximity to the droplet, without contacting the droplet.
