Silk Fibroin as a Resist for Thermal Scanning Probe Lithography

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Samuel Zimmermann

We present for the first time nano-scale patterning of silk fibroin with a thermal scanning probe to locally convert water-insoluble crystalline silk into the water-soluble phase. Our first experiments demonstrate silk as a fully water-based resist for the ...

A transparent silk-fibroin-based triboelectric microgenerator for airflow energy harvesting

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Yinben Guo

We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It th ...

Towards a new generation of fibre-optic chemical sensors based on spider silk threads

Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia

A spider uses up to seven different types of silk, all having specific functions, to build its web. For scientists, native silk - directly extracted from spiders - is a tough, biodegradable and biocompatible thread used mainly for tissue engineering and te ...

Weaving our way towards a new generation of ﬁbre-optic chemical sensors based on spider silk

Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia

From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of preys on its web. Indeed, this primeval material has been shaped over hundreds of millions of years by spiders ...
