Bio-inspired conceptualization of the nano-metering silica tablets. a Scanning electron microscopy of Thalassiosira pseudonana, showing the whole valve and the detail of the porous nanochannels in the insert. Image adapted from [26] and used under CC BY 4.0 license. b Starting from nanopores initially empty, the water molecules and solvated proteins tend to intrude into the silica nanotablets with a characteristic filling time. c Detail of the intrusion of ubiquitin (1UBQ) in a silica nanopore, resulting in reduced mobility of the water molecules due to the electrostatic interactions with the protein and nanopore surfaces
