Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

open access: yesAdvanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.

Amplified Sensitivity in SERS Detection of L1CAM With Silver Plasmonic Mesoporous Silica Capsules on an Imprinted Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents core‐shell Au‐Ag NPs and a novel molecularly imprinted polymer (MIP)‐based material targeting L1CAM. Thionine is used as a monomer to create the MIP on a carbon screen‐printed electrode. Functionalized Au‐AgNCs with Raman reporter 4‐mercaptobenzoic acid and anti‐L1CAM enable selective detection via surface‐enhanced Raman scattering ...

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Hybrid DNA Origami – Graphene Platform for Electrically‐Gated Nanoscale Motion

open access: yesAdvanced Materials Interfaces, EarlyView.
A hybrid DNA origami‐graphene architecture is employed in a nearfield sensing device for optical distance assessment in biosensors and biorecognition purposes. Using Fluorescence Lifetime Imaging Microscopy (FLIM), a nearfield quenching model is verified and test the device response under several electrostatic gating conditions, which leads to changes ...

Impermeable and Elastic Polydimethylsiloxane Film by Parylene‐Caulking for Inflatable Soft Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates poly‐para‐xylylene (parylene)‐caulking of polydimethylsiloxane (PDMS) without loss of its elasticity for use in inflatable soft devices such as a pneumatic balloon actuator (PBA). This study reports updated results using time‐of‐flight secondary ion mass spectrometry and the dependence of characteristics on prepolymer ratio ...

Conjugation Strategies for Low Solubility Proteins to Single‐Walled Carbon Nanotubes as a Sensitive Fluorescent Assay to Protease Activity

open access: yesAdvanced Materials Interfaces, EarlyView.
This study introduces a hybrid conjugation strategy for immobilizing low‐solubility proteins on SWCNTs to enhance fluorescent detection of protease activity. By combining covalent conjugation with non‐covalent polymer wrapping, the method achieves a threefold sensitivity increase, detecting protease activity in 5 minutes for ECM degrading enzymes and ...
