Amphiboles are amazing minerals existing in a wide range of temperature and pressure and accommodating a diversity of elements in their structure. These compounds can be potential functional materials because they exhibit strongly anisotropic properties stemming from their structural anisotropy.

Biomimetic spider silk can be an important tool to understand better the natural counterparts. Moreover, it allows material scientists to produce engineered materials with desired properties. In this case, the response of artificial spider silk to humidity is investigated.
