A DIY $125 liquid–liquid separator
Separating mixtures of immiscible liquids is a critical process in flow chemistry. Andrew Harvie, Jack Herrington, and John deMello have written a paper detailing how to make a useful piece of equipment to separate immiscible liquids for just $125. The project makes use of 3D Printing, a drilled out block of aluminum, a positional servo […]
MiCube: A modular fluorescence microscopy framework
miCube, not to be confused with µCube, is an a open and modular framework for the design and assembly of florescence microscopy optical devices, including devices with TIRF and widefield as well as an advertised confocal capabilities. The miCube has a peer-reviewed manuscript demonstrating it’s performance written by Koen Martens, Sam van Beljouw, Simon van […]
PiVR: $415 to create a VR platform for small creatures
PiVR stands for Raspberry Pi Virtual Reality system. It’s an open-source design published by David Tadres and Matthieu Louis that allows dynamic closed-loop experiments to study unrestrained optogenetic stimulation of neural functions in small creatures. The device tracks a small creature at 50 Hz, and generates light stimulation patterns based on the position of the […]
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, […]
