Here are two new designs for the new diffusion cells. Design_2 could be a better solution as it separates the two connections and uses screws to make the wire contacts to outside circuit.
Please feed back any ideas to improve these designs. Dave and I probably will start working on it some time this week. Thanks.
Hello Everyone, So Now that we have NanoSight in our lab, i decided to run some experiments with different conditions of media and compare the number of particles in each media. We designed this set of experiments like: Water DMEM DMEM + Exosome Free FBS DMEM + FBS ADSC Conditioned Media HDFB Conditioned Media HUVEC…
Hello Everyone, For the next figure in our paper, and to make the transition happens smoothly from Track Etched membranes to NPN membranes, we decided to run the same beads experiment on NPN membranes as well. So Kilean and i started working on these experiments, and the first experiment was to capture and release 100…
For a while now I’ve been running diffusion experiments using bacterial alkaline phosphatase (bAP) as my solute of interest in a solution of 50mM tris buffered saline (TBS) and 20 ug/mL BSA. Initially, the BSA was included as a way of reducing the adsorption of the low concentrations of bAP to the device surfaces —…
As per Chris request, here is a photo with a brief description. Sorry the image is still not good… the surface of the plastic reflects lights and it is transparent, plus I am using a poor camera. But I hope the description is useful and anyway tomorrow we can check it out in the meeting!
There have been differences between the previous long term discoloration studies carried out by myself and Barrett. Couple of reasons speculated for the differences were: 1) Wafer variation (w683 vs w704); w683: has no visible pores, is more amorphous in character, and has many pinholes; w704: 200um series. 2) Silanization treatment (UVO chamber PDMS contamination;…
