Delaware Patent of the Month – March 2022

Humans are trichromatic. This means our visual capabilities are optimal for three wavelength regions – or colors. Humans are most sensitive to reds, greens, and blues. Most birds are tetrachromatic with additional sensitivity to ultraviolet (UV) wavelengths. Most other animals are dichromatic – sensitive to just two wavelength regions. 

Arkion®Life Sciences has designed a product that utilizes these visual capabilities with repellents – or attractants – to increase their effectiveness. Through intensive research, they found the addition of a visual cue can increase an animal’s response to attractants and repellents by approximately 5%. 

Visual cues can include the use of titanium (IV) oxides, siloxanes, and UV-absorbing or UV-reflective agents. This is because the dichromatic animal is not maximally sensitive to the wavelength of the repellent or attractant on its own. The combination of the visual cue with the effects of the repellent or attractant increase the animal’s response.

For instance, in experiments with rodents, the company found that rabbits were more likely to be repelled when confronted with a UV-absorbent, postingestive repellent than if they were confronted with just the repellent or just the visual cue.

Arkion Life Sciences is a technology based company that discovers, develops, manufactures and markets environmentally friendly products and technology that provides modern solutions to today’s problems. Both repellents and attractants have their place in the world. Repellents are essential to protecting crops and preventing opportunistic rabbits from eating up your garden. Attractants are used for a breadth of reasons, including attracting wild animals to your feeders for recreational entertainment, or attracting target-animals for use in experiments and studies. Regardless of the purpose, an improved rate of the desired response is always preferred.
