Sensitive sensors could be made from spider silk fibre

Physicists have developed a way to help structurally modify spider silk fibre and microweld it with various metals and carbon-based materials1 — a method that could be useful for making various spider-silk-based microstructures such as ultrasensitive sensors. Spider silk is a tough and lightweight biomaterial. However, existing techniques that modify silk fibres using ultraviolet lightRead more about Sensitive sensors could be made from spider silk fibre[…]

How a microscopic bio-heat engine works

How a microscopic bio-heat engine works

Physicists have designed a microscopic heat engine by optically trapping a colloidal bead in a bacterial bath1. The heat engine could potentially be used in nano-electromechanical and microfluidic devices. A conventional macroscopic heat engine converts heat energy into mechanical work by confining a few cubic centimetres of gas between a moving piston and its walls.Read more about How a microscopic bio-heat engine works[…]
