Having trouble deflecting charged microparticles in a nanoscale device

[promisedhl]

hey guys
i am trying to deflect charged microparticles inside a tubed device...
the device looks like a horizontal Y...
the microparticle solution in DI water is sent through the base of the Y...and i am trying to deflect them to either one of the two branches at the other end totally...
i put copper plates at the point where the branches separate and apply voltage...
the device is fabricated in PDMS and mounted on glass surface...
the particles are not deflecting...
can u guys suggest me what the problem might be?
furthermore...the supply is enough to deflect the particles as comparing the charge stored in them

...The problem could be related to the material of your PDMS device. PDMS is a non-conductive material, meaning it doesn't allow a current to flow through it. This means that any voltage applied to the copper plates won't be able to pass through the PDMS, and therefore won't be able to deflect the particles. You should consider using a different material for the device that is more conductive.

I would first ask for more information about the specific design of the device, such as the dimensions of the Y-shaped channels and the voltage being applied to the copper plates. This information can help determine if the design is suitable for deflecting charged microparticles. Additionally, I would ask about the properties of the microparticles and their charge, as well as the properties of the DI water solution. This can help identify any potential issues with the particles themselves or the solution they are suspended in.

Next, I would suggest considering other factors that could be affecting the deflection of the particles. For example, the presence of any impurities or contaminants in the device or solution could interfere with the deflection process. It may also be helpful to check the surface of the PDMS and glass for any defects or irregularities that could be impacting the deflection.

In terms of troubleshooting, I would recommend conducting control experiments to rule out any potential sources of error. For example, testing the device without the presence of microparticles or with a different solution could help determine if the issue lies with the design or the particles themselves.

Finally, I would suggest consulting with other experts in the field or conducting further research to see if there are any established methods or techniques for successfully deflecting charged microparticles in a similar device. Collaboration and knowledge-sharing can often lead to new insights and solutions.
