Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

Advanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Saddle-splay modulus of a particle-laden fluid interface [PDF]

, 2008
The scaled-particle theory equation of state for the two-dimensional hard-disk fluid on a curved surface is proposed and used to determine the saddle-splay modulus of a particle-laden fluid interface.

Fluorinated alcohol as Pickering emulsion demulsifier

Next Materials
This short paper examines the effectiveness of a fluorinated alcohol (1 H,1 H,2 H,2H-perfluorodecanol: FC10OH) as demulsifiers for Pickering emulsions by assessing interfacial tension and visually observing the stability of the emulsified samples.

Preparation of Porous MOF‐Polymer Composites via High Internal Phase Pickering Emulsions for Dye Adsorption Applications

Chemistry – A European Journal, EarlyView.
A versatile method was developed to fabricate hierarchically porous monoliths using UiO‐66/TOCNC composites as Pickering emulsion stabilizers. The resulting polyHIPEs, produced under mild and scalable conditions, showed confirmed structural integrity through TGA, XRD, SEM, BET, and FT‐IR.

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

The Canadian Journal of Chemical Engineering, EarlyView.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...

Contact-line pinning controls how quickly colloidal particles equilibrate with liquid interfaces

, 2016
Previous experiments have shown that spherical colloidal particles relax to equilibrium slowly after they adsorb to a liquid-liquid interface, despite the large interfacial energy gradient driving the adsorption. The slow relaxation has been explained in

Liquid marbles: principles and applications [PDF]

, 2011
The ability of particles to adhere to a fluid–fluid interface can stabilize the formation of an emulsion. When the encapsulated fluid is a liquid and the fluid in which it is immersed is air, the object formed is called a “Liquid Marble”. Here we discuss
