Each colorimetric test spot has one or more sensing chemicals chemically attached onto a porous support material. The porous support material has at least one exposed surface configured to absorb a body fluid. The one or more sensing chemicals are configured to change a color in response to a presence of a target drug in the body fluid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Colorimetric drug test strip using porous support material","description":"A test strip includes a substantially transparent substrate and one or more colorimetric test spots on the transparent substrate.
