AttoBright: A single-molecule confocal system built from a 3D-printed scaffold

The AttoBright is a 10×20 cm single-molecule confocal system capable of single photon counting and fluorescence correlation spectroscopy. The scaffolding is designed to minimize the amount of optical components needed, and make those optical components easy to install with automated alignment. A paper by James Brown, Arnaud Bauer, Mark Polinkovsky, Akshay Bhumkar, DominicHunter, Katharina Gaus, […]

The Wally120 OpenKnit Machine

Inspired by the work of Sabetta Matsumoto and Julianna Abel, we have been looking at programmable automatic knitting machines on the cheap. Several scientists research the creation of unique metamaterials by programming them with lattices of slip-knots, a process colloquially known as knitting. A low-end industrial programmable knitting machine, from Shima Seiki costs between $90,000 […]

A qPCR device for $300

A real-time polymerase chain reaction (real-time PCR), or quantitative polymerase chain reaction (qPCR), is a modification to normal PCR where one monitors the amplification of a targeted DNA molecule during the PCR. We’ve written before about our favorite cheap solutions for PCR, but check out this interesting paper on building your own quantitative-PCR (qPCR) machine written by Geoffrey Mulberry, […]
