What I want to do
Try to detect specific elements/molecules using acrylic paint to filter waves of light down a piece of optic fibre & into a light sensor.
Questions and next steps
Why Acrylic Paint? Because it is Translucent - so will hopefully only let light that is the wavelength targeted enter the optic fibre & be detected by the light sensor.
What next? Updating this page with a better explanation of the science involved & then performing experiments to see if it works!
