The biggest hurdle was finding these elements. Rare earths are often present in tiny concentrations—parts per billion—making them a "needle in a haystack" to detect without expensive, bulky lab equipment.

In 2021, researchers at Penn State University developed a game-changing luminescent sensor: New sensor able to detect rare earths in acid m...

: When the protein binds to a specific element like terbium , it glows green under UV light. The biggest hurdle was finding these elements

: It works in highly acidic environments and is as accurate as the "gold standard" laboratory mass spectrometry (ICP-MS), but is potentially portable and far cheaper. Impact: Turning Waste Into Wealth bulky lab equipment. In 2021
