Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

For content creators, this commercial evolution might create new opportunities to monetize AI visibility beyond indirect traffic benefits. If platforms begin sharing revenue with cited sources, strong AI visibility could become directly profitable. If sponsored placements become normalized, there might be ways to amplify your organic visibility through paid promotion similar to how PPC complements SEO.
