Fear of the Duck

“Fear of the duck, fear of the duck
I have a constant fear that something’s always near
Fear of the duck, fear of the duck
I have a phobia that someone’s always there”

Finally, after I don’t know how many months of teaching and writing, I’m back!!! Back in the lab.
To celebrate this awesome moment, here some ducks:

During our last course (Nanomedicine) we used a home(lab)-developed micelles for showing the students how a multimodal imaging probe works (fluorescence and MRI contrast agent). Usually for this kind of experiments a “phantom mouse” is used, but we thought that a mouse is kind of boring. What’s better than a duck???
We printed a mold for making small ducks (here on thingverse) and we had quite some fun with agarose ducks:
agarose pdms duck

left an agarose duck, and right a PDMS duck (not really for depth penetration study, but I love PDMS so….)

phantom duck2

Here the dyes injected in the head (red) illuminated by a UV lamp.

phantom duck1

Same duck, this time illuminated by a laser (right).

Then we moved for some MRI experiments… Have you ever seen a 2cm NMR tube?

2cm NMR tube

Well, now you have :) (and a comparison with a standard NMR tube). See how the duck is happy to get a bath in the NMR tube? Now let’s try to measure something…

MRI duck1

This is an MRI of the agarose duck. In white the contrast agent injected in the duck. the black stuff is just air. Nice isn’t it?

MRI duck2

Another duck another MRI. This time without contrast agent (and also without air bubbles inside the agarose…..)


But, wait a minute, the students also formed some quantum dots during the course…. Shall we put them in agarose??? Well, why not?

QD = Quantum Ducks:

quantum ducks 1 quantum ducks 2 quantum ducks 3


Luckily no students suffered from anatidaephobia, but in any case, if you are afraid of the ducks, you are not alone:

    Aren’t quantum dot particles wildly carcinogenic through the same mechanism that asbestos and nanoparticulate coal is?
