-Materials Needed:
+  * Lab Coat
-Activated PDMS surface (for bonding)
-Activated glass surface (for bonding)
+**Materials Needed:**
-Aluminum foil

-Tools Needed:
+  * Activated glass surface (for bonding)
-Oven
+  * Aluminum foil
-Tweezers
-Procedure:
+**Tools Needed:**
-The hydrophilicity of activated surfaces decreases rapidly with time. Perform this procedure immediately after surface activation. Use clean implements. Any dirt or contamination will negatively impact the device bonding.
+  * Oven
-Using clean tweezers, carefully pick up the two pieces to be activated. Bring the activated surfaces in contact with each other.
+  * Tweezers
-Work from one corner of the device to the other, gently pressing the surface to eliminate bubbles.
-Create a tray from aluminum foil, and place the device on it. This will facilitate baking the device.
+**Procedure:**
-Bake the joined device at 120 C for 20 minutes. This will create a permanent bond between the glass and the PDMS. (A drip tray is not necessary)
