Congrats to Guolin (@GuolinYun) for the publication of his work on a very interesting liquid metal composite material with anisotropic and unconventional piezoconductivity in Matter (@Matter_CP). Thank you to my friends (@DickeyGroupNCSU

@HenryMicro36 @SerendipityWrk Cool poster! Did you measure the 2D fluorescence or 3D's? I mean the cell culture is in 3D, so the cell may exhibit different fluorescence from different angles.

[Dan Yuan @DanYuan20]

@PabloMPancorbo @SerendipityWrk Great work! How long does it take to kill the cancer cells? Will the heating has a potential side effect for other cells or tissues?

[Dan Yuan @DanYuan20]

@farmistead @SerendipityWrk Great work! What kind of solution did you use to induce different viscosity? Do you think the elastic effect may contribute the cell deformability?

[Dan Yuan @DanYuan20]

@Christa_pb @SerendipityWrk Very interesting work! How did you introduce microbubbles inside the microgel? Can you control the drug release speed?

[Dan Yuan @DanYuan20]

@LimeiLiu1 @SerendipityWrk Very cool work! I have a few questions. What's DSS? What controls the release of DSS? Why the side releasing more DSS has a lower surface tension?

[Dan Yuan @DanYuan20]

@ISOZAKIAkihiro @KangHee_snow @SerendipityWrk @nukkie66 Thank you!

[Dan Yuan @DanYuan20]

@farmistead @SerendipityWrk Very good questions! The blockage ratio is dependent on both the particle size and the channel size. I didn't see particle deformability has effect for focusing in this work. Similar sizes would be difficult, but it's possible to separate objects with a size difference of >1um.

I am Dan Yuan. My presentation title is ‘Viscoelastic microfluidics-based sheathless separation of microalgae from bacteria using a simple straight channel’.

@ISOZAKIAkihiro @KangHee_snow @SerendipityWrk Got it! Thank you Isozaki-san!

[Dan Yuan @DanYuan20]

@uuyonihsoh @nukkie66 @SerendipityWrk I got it. Thank you Hoshino-san!

[Dan Yuan @DanYuan20]

@YutaNakagawa5 @SerendipityWrk Thank you Yuta! This method is size-dependent separation, so it's possible to separate a sample that has more than 2 constituents as long as they have ideal size difference.

[Dan Yuan @DanYuan20]

@JGaladePablo @SerendipityWrk Thank you Julia! I didn't grow the bacteria-free microalgae, but your suggestion is quite valuable. This method can be used to purify a strain from bacterial contaminants as long as the bacterial contaminants have a certain size difference with the cell strain.

[Dan Yuan @DanYuan20]

@MiyukiXu @SerendipityWrk Very good question! The low flow rate is one limitation. Currently, we've been thinking to use another kind of viscoelastic fluid such as Hyaluronic Acid solution instead of PEO to increase the flow rate. Another way is to parallelize the channels.

[Dan Yuan @DanYuan20]

@ISOZAKIAkihiro @KangHee_snow @SerendipityWrk Different types of yeast cells may have different shapes. Also, for the same type of yeast cell, they would have different shapes in the different cell cycles. Therefore, is it possible to tell if the cells are from different cell types or from different cell cycles?

[Dan Yuan @DanYuan20]

@uuyonihsoh @nukkie66 @SerendipityWrk Is this polymer material totally biocompatible?

[Dan Yuan @DanYuan20]

@uuyonihsoh @nukkie66 @SerendipityWrk Very nice talk Hoshino-san! Could you explain a bit more about the GIF? What reaction is happening in the two mouse?

[Dan Yuan @DanYuan20]

@Mario33950212 @SerendipityWrk @GuolinYun @ShiyangTang How is the stability of the liquid metal droplet? Will it be merged with each other along time?
