Synthetic Spider Silk

A line-art diagram of the microfluidic device. On the left, in red text, it says "Fibrillization trigger (CPB pH 5.0). There is a rectangular outline of the chip in grey, with a sideways trapezoid on the left side narrowing until it becomes an arrow on the right. At the right is an inset picture of the semi-transparent microfluidic chip and the text "Negative Pressure (Pultrusion)." Above the trapezoid is the green text "MaSp2 solution" and below is "LLPS trigger (CPB pH 7.0)" in purple. The green, purple, and red text correspond with inlets labeld 1, 2, and 3, respectively. Three regions along the arrow-like channel from left to right are labeled "LLPS region," "pH drop," and in a much longer final section "Fiber assembly region."

While spider silk proteins are something you can make in your garage, making useful drag line fibers has proved a daunting challenge. Now, a team of scientists from Japan and …read more Continue reading Synthetic Spider Silk→

Miles the Spider Robot

Posted on August 6, 2020 by Orlando Hoilett

Who doesn’t love robotic spiders? Today’s biomimetic robot comes in the form of Miles, the quadruped spider robot from [_Robox].

Miles uses twelve servos to control its motion, three on each of its legs, and also includes a standard HC-SR04 ultrasonic distance sensor for some obstacle avoidance capabilities. Twelve servos …read more

Arachnid Ale Uses Yeast to Make Spider Silk

Posted on November 5, 2018 by Brian McEvoy

Many people who read Hackaday hold the title of “Webmaster” but [The Thought Emporium] is after slightly different credentials with the same title. He aims to modify a strain of yeast to produce spider silk. Charlotte’s Web didn’t go into great detail about the different types of silk that a spider can produce, but the video and screencap after the break give a rundown of how spiders make different types of silk, and that each species of spider makes a unique silk. For this experiment, the desired silk is “beta sheets” which the video explains are hard and strong.
