Portable System Implementations: What we DID…
The image on the left is our implementation setup.
The LED is at the bottom.
The biosensor is in the middle with our immobilized biosample.
On the top is our smartphone to take pictures
Optical point-of-care sensors
Demand for method of disease biomarker screening that is sensitive, convenient, and accessible
Plasmonic optical biosensors have high potential for sensitive biomarker detection with a relevant dynamic range for human disease but current instrumentation and setups are bulky and expensive
Second implementation using a photocell
What We HAVE:
Let’s Talk GRAPH:
Refractive Index
These are some of the images taken from an Iphone 6.
Figure. Sensing using refractive index change. (a) Increasing Intensity with increasing refractive index (sucrose concentration) (b) Images taken from sucrose at different concentration.
The image on the left is of our second setup using an LED.
Sample is inserted
Refraction index of sample affects amount of light to photoresistor
Can measure current changes to see effect
Who made it POSSIBLE?
We would like to express our gratitude to our mentor, Lisa Plucinski, for giving us this amazing opportunity to work on this project with her. This research has helped us understand the kind of focus and dedication required for research and we hope to implement what we learned in our future endeavours.
