Get your hydrogel, throw in some silver nanoparticles, treat with a laser and you have a hologram. When that interacts with a substance, like insulin it will naturally adjust the color of the hologram giving a diagnosis.

A new hydrogel uses holograms to warn you about your health

This new hydrogel concept uses a simple hydrogel that has been “impregnated” with silver nanoparticles. A specially developed treatment with a laser, just a single short burst upon manufacturing, aligns these silver particles in a three-dimensional hologram.

When the hydrogel comes into contact with certain trigger substances (like glucose, or insulin) it will physically deform relative to the concentration of the chemical. So, a higher blood glucose level results in a more deformed gel — which naturally adjusts the color of the hologram.

This allows the hologram to have analog output of information. That is, it can display not just a binary yes-no on healthy blood glucose, but can slowly darken to let the user know when they are approaching unsafe levels.

This tech combines quick response time with low cost and ease of use…
