Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Enhancing Magnetic Hyperthermia at the Cell Membrane by Anchoring 92R‐Functionalized Magnetic Nanoparticles to Low‐Endocytic CCR9 Surface Receptors

open access: yesAdvanced Healthcare Materials, EarlyView.
We present a strategy to enhance magnetic hyperthermia therapy by modulating nanoparticle–cell interactions. Antibody‐functionalized magnetic nanoparticles targeting the low‐internalizing CCR9 receptor enable spatially controlled membrane anchoring, reducing aggregation and maximizing heat generation under alternating magnetic fields.

Acute toxicity of arsenic and oxidative stress responses in the embryonic development of the common South American toad Rhinella arenarum [PDF]

open access: yes, 2015
Arsenic (As), a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01mg/L and 15mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the

Machine Learning‐Assisted Infectious Disease Detection in Low‐Income Areas: Toward Rapid Triage of Dengue and Zika Virus Using Open‐Source Hardware

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

A Multiepitope‐Based Lateral Flow Assay for Leprosy Antibodies

open access: yesAnalysis &Sensing, EarlyView.
An innovative lateral flow assay for leprosy diagnosis is based on gold nanoparticles and synthetic Mycobacterium leprae epitopes conjugated to keyhole limpet hemocyanin protein to enhance antibody detection. This strategy provides a rapid, accurate, and low‐cost approach for resource‐limited settings, enabling the early detection of infection. Leprosy

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...
