Nanoenabled Phytochemical Mining: Gold Nanoparticle‐Mediated Recovery of Low‐Polar Secondary Metabolites From Plant Extract

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Green‐synthesized gold nanoparticles serve as tunable nanoadsorbents for selectively enriching low‐polarity secondary metabolites from Hypericum perforatum extracts. Structure‐ and polarity‐dependent interactions, optimized by solvent composition and incubation time, enable efficient recovery of phloroglucinols and xanthones for phytochemical ...

Functional Traits Mediate Physico‐Chemical Niche Differentiation of Epiphytic Lichens and Bryophytes in Temperate Forests

open access: yesJournal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...
