Plastic is making our lives easier in many ways. Products made from plastic are flexible, durable, lightweight and resistant to high wear and corrosion. However, there is a huge downside: Plastic waste has become a massive threat. More than 10 million tons of waste end up in the oceans every year. Millions of marine animals fall victim to these remnants of our throw-away-society.

Lateral flow immunoassays are a practical tool for drugs of abuse screening, especially in point-of-care, onsite screening and, of course, for roadside drug testing. They are easy to use, cost efficient, with a very short time to result. Most lateral flow immunoassay tests are non-instrumental and rely on the visual detection of colored test lines. The interpretation of results is primarily based on a user’s perception of the color intensity of the test lines. Naturally, this color perception is affected by various factors, especially by an individual’s visual acuity and the ambient light conditions.
