Physical Vapor Deposition Method

>>Result page is here

Overview

Deposition is a method for forming a metal thin film on the surface of the substrate.
In this project, Gold and Chromium were deposited on the polystyrene surface in order to conjugate specific DNA onto the determined location on the surface.

Physical Vapor Deposition Method

1st Deposition

First, we deposit gold on the polystyrene-bead in order to make gold hemisphered body.

2nd Deposition

Next, we change the direction of beads, and deposit chromium on the body.
Then we pick up polystyrene-bead, which are deposited by quarter gold and half chromium.
By chromium capping, this "head part" is prevented to conjyugate DNA strands, so platinum only mounted at the rear.

After PVD

Through twice of physical vapor deposition,
  • we conjugate thiol modified DNA onto gold part.
  • we conjugate amino modified DNA onto polystyrene part.
  • There are no DNA staple strands on chromium hemisphere.
Therefore, platinum particles can't conjugate onto chromium hemisphere.
As a result, JET starts to move toward chromium hemisphere heading.
