Preparing iDISCO samples

iDISCO samples tend to be small and hard which allows them to be clamped in a special sample holder. As the index of the imaging medium (dibenzyl ether, n = 1.562) is higher than typical glasses used for cuvettes, it is recommended to image the sample without a sample cuvette, just with a big (30x30/40x40 or 50x50 mm) outer cuvette.

Mounting samples

DBE and BABB tend to dissolve several types of plastic. 3D-printed parts made from polyamide (nylon) are resistant to these solvents. Some examples of clamping holders are shown below.

Clamp 1 (polyamide)

The clamp consists of 2 parts, the moving part is held by friction. The clamp can be 3D printed from our design files (IPT, STL, STP). We use industrial SLS printer and PA12 (polyamide, nylon) for high-resolution printing of teeth and other small features.

Clamp no cuvette

Clamp 2 (polyamide)

Also 3D printed from polyamide. The sample can be clamped between two Nylon screws. DBE sample holder

Clamp 3 (Alu)

Imaging

For imaging in iDISCO, the large cuvette is exchanged with one filled with DBE and the ventilation duct set up as close as possible to the cuvette.

DBE sample holder

The samples are usually so transparent that they are almost invisible when the laser excitation is off.
