Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

open access: yesRiver, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Indocyanine Green–Inspired Polymeric Chromophores With Intrinsic Photostability for Near‐Infrared Imaging

open access: yesSmall, EarlyView.
Indocyanine green (ICG) is widely used for near‐infrared imaging but suffers from poor photostability. Here, an indocyanine green–inspired polymeric NIR chromophore is introduced, exhibiting intrinsically enhanced photostability and biocompatibility.
