Arduino Uno based spin coater for thin film deposition

 Arduino Uno based spin coater for thin film deposition

Nano thin films can be fabricated by a number of deposition techniques. Among these, Sol-Gel spin coating technique is considered to be very effective in fabricating thin films. Commercially available spin coating devices are expensive so I designed my own device with the help Arduino Uno microcontroller unit. On this device, I published an article in "Advanced Materials Research", a UGC Care listed journal and can find at https://www.scientific.net/AMR.1169.49

Got certificate from NPTEL in "Experimental Nanobiotechnology" course



Experimental Nanobiotechnology (NPTEL Course)
The NPTEL course "Experimental Nano biotechnology" was presented by Prof: Gopinath, Dept. of Biosciences and Bioengineering, IIT Roorkee. The framing of this course was very useful and good. It includes fabrication of nanomaterials, their characterization techniques and their biological applications. I am very thankful to the course organizers and to the instructor.
