Nature’s little engineers: How proteins make ice and gemstones

 

 

 

Proteins can act as Nature’s engineers at interfaces and manipulate both hard and soft tissue – they can shape biominerals, manipulate cell membranes and sense external stimuli. Despite the apparent importance for chemists working in the fields of biomineralization, surface engineering and drug delivery the molecular mechanisms behind interfacial protein action have largely remained elusive. We use surface vibrational spectroscopy combined with computer simulations to determine the structure and the mode of action by which these proteins interact with and manipulate interfaces. Here, we discuss recent advances in the study of protein driven nucleation: The assembly of intricate mineral structures found within marine animals, teeth and bone and the growth of ice crystals by specialized ice-nucleating proteins.
