By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
His move to the startup world was inspired by Clayton Christensen’s The Innovator’s Dilemma, which argues that market leaders, by nature, are often set up to fail. “This thesis made me really understand how the technology industry was going to be much bigger, much faster than most thought in the late ’90s,” he told Authority Magazine in 2021. “This made me take the risk of working at my first startup because I believed that big companies were at risk of being disrupted due to the advent of the internet and mobile phones.”
