Molecular Biomimetics - Making materials one molecule at a time, via the Biology’s ways, allows an intricate control of nano- and microstructures that permit tailoring functional properties towards practical applications. Molecular recognition & self-assembly, two key fundamental phenomena provide key means to implement genetic design of materials and systems, under environmentally-benign conditions, with interdisciplinary implementations as exemplified from the cover stories in these major journals, representing diverse fields, strong indicator that engineered peptides are impacting wide range of science & technology.
