Enzymatic etching used to build nanoscale surface topologies

from Wiley via R&D Magazine

In living systems, complex nano- and microscale structures perform a host of physical and biological functions. While 2-D patterns can be recreated fairly well with techniques like microlithography, 3-D structures represent a big challenge. Researchers have now reported a new method for the lithography-free etching of complex surface motifs with the use of biodegradable polymers and enzymes. more
