During the brief meeting this week, the alternative cylindrical design that was discussed in last meeting was published in CAD and its dimensions were discussed in this week’s meeting as well.
Regarding the unibody design, we ran some experiments to improve the integrity of channel embedded in the gel to achieve the goal to maintain an open conduit for pressure driven flow. The measures that were taken during the experiments include increasing the channel size (radius), incubating the loaded gel (within testing chamber) under higher temperature and so on. Lastly, out group also discussed the future plan that to merge the features of two designs we are currently testing into one. Namely, after the improvement of conduit fabrication in the unibody design, the procedure shall be applied to the cylindrical design to improve its stability for diffusion measurement performance. In the end, attached are the top, middle and bottom compartment of the new cylindrical design. The top piece shall be holding the initial load of drug solution, the middle compartment shall be holding the gel (agarose, matrigel, etc.), the bottom piece shall serve the purpose of end fluid collection. More details of the design will be brought into next week’s report after more group discussions and experiments.
