Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

open access: yesSmall, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Beads‐on‐a‐Tip testing for ultrasensitive antigen detection across a large dynamic range

open access: yesSmart Molecules, EarlyView.
Non‐specific adsorption on nitrocellulose membranes limits the sensitivity of conventional lateral flow immunoassays. Here, we present a Beads‐on‐a‐Tip immunoassay that replaces the membrane with magnetic beads for antigen capture and enrichment, while employing upconversion nanoparticles as background‐free luminescent reporters.

New fabrication technique for highly sensitive qPlus sensor with well-defined spring constant

open access: yes, 2015
A new technique for the fabrication of highly sensitive qPlus sensor for atomic force microscopy (AFM) is described. Focused ion beam was used to cut then weld onto a bare quartz tuning fork a sharp micro-tip from an electrochemically etched tungsten ...

Selective Wettability–Driven Evaporation‐Enhanced Redox Cycling for Robust and Ultrasensitive Detection of Viral Particles

open access: yesSmall Methods, EarlyView.
ABSTRACT Timely detection of viral infections, particularly in settings outside centralized laboratories, is essential for controlling outbreaks. Small electrochemical biosensors are appealing because they are fast, require microliter sample volumes, and can be integrated into portable devices.

Effectiveness and durability of mRNA-1273 BA.4/BA.5 bivalent vaccine (mRNA-1273.222) against SARS-CoV-2 BA.4/BA.5 and XBB sublineages

open access: yesHuman Vaccines & Immunotherapeutics
Emerging SARS-CoV-2 sublineages continue to cause serious COVID-19 disease, but most individuals have not received any COVID-19 vaccine for >1 year. Assessment of long-term effectiveness of bivalent COVID-19 vaccines against circulating sublineages is ...
