Color-Changing Contacts Monitor Monitor Glucose Levels
The University of Western Ontario
Diabetics may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colours – replacing the need to routinely draw blood throughout the day.
The non-invasive technology, developed by Chemical and Biochemical Engineering professor Jin Zhang at The University of Western Ontario, uses extremely small nanoparticles embedded into the hydrogel lenses. These engineered nanoparticles react with glucose molecules found in tears, causing a chemical reaction that changes their colour.
Does Red Weigh More Than Blue?
Let’s step into the wayback machine and talk about some research that even the psychologists among us might not be aware of (I certainly wasn’t). It seems that at the turn of the 20th century, many psychologists and psychophysicists (including the father of psychophysics, Gustave Fechner) were interested in aesthetics. Out of this interest came the idea, inspired by the work of Helmholtz and others, that geometrical figures had a certain “energy,” which influenced the subjective quality of their combinations…
Bullough believed that this canon was the result of different colors having different weights (which he saw as analogous to the energies of geometrical figures). Here’s how he describes the weight of colors: Continue Reading.
Photolactiv cells look like “golden snowflakes”
The glitter-sized solar sequins are made from crystalline silicon and use 100 times less material to generate the same amount of electricity as standard solar cells made from 6-inch square solar wafers
