Nanoscale Lithography and Thermometry with Thermal Scanning Probes

Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in which a heated atomic force microscope tip locally modifies a sample material. Due to the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...

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 ...

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 ...

Thermal-responsive biodegradable composite membrane for drug delivery application

Ya Wang

Drug delivery systems have been engineered in order to improve therapeutic performance and reduce the side effects of conventional delivery system like oral ingestion, subcutaneous injection [1-2]. There exist several types of drug delivery systems, among ...

A silk-fibroin-based transparent triboelectric generator suitable for autonomous sensor network

Jürgen Brugger, Xiao Sheng Zhang

In recent years, a new electriﬁcation-based mechanism called triboelectric generator (TEG) has been demonstrated as a stable and renewable power source to convert ambient energy into remarkable electrical output. Various TEG conﬁgurations have been propose ...

Silk Hydrogels as Soft Substrates for Neural Tissue Engineering

Jeffrey Alan Hubbell, Federico Tortelli, Amy Marie Hopkins

There is great need for soft biomaterials that match the stiffness of human tissues for tissue engineering and regeneration. Hydrogels are frequently employed for extracellular matrix functionalization and to provide appropriate mechanical cues. It is chal ...

The effect of lactose-conjugated silk biomaterials on the development of fibrogenic fibroblasts

Boris Hinz

Surface properties of implanted biomaterials can cause fibrotic tissue reactions by stimulating differentiation of host fibroblasts into contractile myofibroblasts. Silk fibroin (SF) protein has been used as biomaterial in pure and blended form. however, i ...
