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

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

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 ...

Spider silk: a novel optical fibre for biochemical sensing

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

Whilst being thoroughly used in the textile industry and biomedical sector, silk has not yet been exploited for fibre optics-based sensing although silk fibres directly obtained from spiders can guide light and have shown early promises to being sensitive ...

Shedding light on the optical properties of spider silk fiber

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

Optical characterisation of a Nephila edulis spider dragline silk is performed. The silk fiber transmits light up to 1400 nm with a propagation loss of ∼9 dB/cm and birefringence of 8×10−3 measured at 1302 nm. ...

Membrane potential correlates of sensory perception in mouse barrel cortex

Carl Petersen, Shankar Sachidhanandam, Yves Emile Alfred Kremer, Varun Sreenivasan, Alexandros Kyriakatos

Neocortical activity can evoke sensory percepts, but the cellular mechanisms remain poorly understood. We trained mice to detect single brief whisker stimuli and report perceived stimuli by licking to obtain a reward. Pharmacological inactivation and optog ...

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 ...

Spatiotemporal dynamics of cortical sensorimotor integration in behaving mice

Carl Petersen, Rachel Aronoff

Tactile information is actively acquired and processed in the brain through concerted interactions between movement and sensation. Somatosensory input is often the result of self-generated movement during the active touch of objects, and conversely, sensor ...
