Graphical Abstract

Proteins in focus: Dynamically tunable protein microdevices were built up by a simple “top-down”, maskless, femtosecond laser direct writing approach with bovine serum albumin. This technique was used to produce biocompatible microlenses that swell and shrink reversibly in response to changes in the pH of the surrounding solution. These responses to environmental stimuli can be used to focus the microlenses.
