A simple, versatile and reliable method of microstructuring solid supports using micropatterned gels was described. It was demonstrated that micropatterned hydrogel stamps can be used to remove material from solid surfaces and can thus be used to microstructure metals, glasses and crystals with micrometer-scale precision. The immersion wet stamping (i-WETS) technique proved equally successful in microstructuring surfaces of monocrystals with depths of the depressions up to 80 μm, sharp edges and lateral spreading less than 5% of the diameter of the stamped features. It was shown that in specific applications, it might be necessary to use hydrogels other than agarose to make the stamps compatible with desirable etchants.
