Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Fluorination: A strategy to tune the interactions of molecules and nanoscale systems with biological matter

FEBS Open Bio, EarlyView.
This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.

Colloidal ordered assemblies in a polymer shell - A novel type of magnetic nanobeads for theranostic applications [PDF]

, 2013
We present the synthesis of polymer embedded colloidal ordered assemblies, built from highly ordered superparamagnetic manganese iron oxide nanocrystals. Each assembly is wrapped into a thin polymer shell.

Rationally engineered polymeric interfaces for selective and dynamic recognition of vesicular agents

FEBS Open Bio, EarlyView.
This review explores how molecularly imprinted polymers can be engineered to recognize complex nanoscale vesicles, including extracellular vesicles and membrane‐enveloped viruses. By tailoring polymer cavities to vesicle surface chemistry and structure, these synthetic receptors support selective detection, separation, and integration with optical ...

Preparation of Water Based Magnetic Fluid Dispersing Colloidal Metallic Iron.

Journal of the Japan Society of Powder and Powder Metallurgy, 1991
The α-Fe particles were prepared by reducing the ferrous ion in sodium borohydride aqueous solution in the presence of surfactant, sodium oleate. The particles prepared were dispersed stably in tetramethylammonium (TMA) hydroxide aqueous solution with sodium dodecylbenzenesulfonate (SDBS).
