Usnea antarctica (James Ross Island, Antarctica) and Usnea subfloridana (Uludağ, Turkey) Incorporated Hybrid Nanoflowers with Their Intrinsic Catalytic and Antimicrobial Activities
Abstract Herein, we used lichen extracts, for the first time, in formation of organic‐inorganic nanoflowers and we utilized them as novel nanobiocatalyst and antimicrobial agents. Two lichen species, Usnea Antarctica ( U. Antarctica ) and Usnea subfloridana ( U. subfloridana ) were collected from Ja...
