Lasers based on biomaterials known as Generally‐Recognized‐As‐Safe (GRAS) substances approved by the U.S. Food and Drug Administration (FDA) are demonstrated. Vitamin B2‐doped microdroplet lasers are generated and trapped on a super‐hydrophobic poly‐L‐lactic acid substrate. The spheres support whispering gallery mode lasing at optical pump energies as low as 15 nJ per pulse (≈1 kW/mm 2 ).
