A Rapid and Sensitive Method for the Determination of Chitosan Concentration by NMR Relaxometry

open access: yesMagnetic Resonance in Chemistry, EarlyView.
ABSTRACT A rapid, reagent‐free method for the quantification of chitosan in aqueous solutions was developed using 1H nuclear magnetic resonance (NMR) relaxometry. Transverse relaxation times (T2) of chitosan solutions (5–1000 mg/L) were measured with a Carr–Purcell–Meiboom–Gill (CPMG) sequence on a benchtop NMR relaxometer.

Inkjet Printing of Keratin‐Based Ink Formulation

open access: yesJournal of Polymer Science, EarlyView.
Keratin‐based inks were formulated and optimized for inkjet printing by tuning rheological and interfacial properties using sodium alginate and surfactants. The resulting formulations enable stable jetting and uniform film formation, demonstrating the feasibility of digitally printing biocompatible, protein‐based materials for skin‐mimicking and ...

Dissolution‐Controlled Phase Separation of Cs+/Rb+ in High‐Salinity Brines via All‐Inorganic Prussian Blue Analogs

open access: yesRare Metals, EarlyView.
ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Nasal Delivery of mRNA Using Thermoresponsive Gellable Aqueous Biphasic Systems

open access: yesSmall, EarlyView.
Nasal delivery of mRNA using gellable aqueous biphasic systems (ABS) represents a noninvasive alternative while reducing the need for trained professionals and cold chain storage. Composed of gelatin, PEG, and water, these thermoresponsive hydrogels ensure controlled mRNA delivery and prolonged retention at the nasal mucosa, improving transfection ...
