Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

open access: yesAdvanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Lipid Nanoparticle Co‐Delivery of mRNA and a Small Molecule Drug for Oral Cancer Chemoimmunotherapy

open access: yesAdvanced Materials, EarlyView.
Co‐encapsulation of p53 mRNA and the small molecule ciclopirox within a lipid nanoparticle yields an all‐in‐one chemoimmunotherapy for oral squamous cell carcinoma. The platform engages caspase‐driven apoptosis in cancer cells while repolarizing tumor‐associated macrophages, achieving tumor reduction in both p53‐susceptible and p53‐resistant models and

Mechanism‐Driven Nanoformulations for Cognitive Impairment Induced by Intermittent Hypoxia and Periodontitis

open access: yesAdvanced Materials, EarlyView.
Clinically, intermittent hypoxia (IH) is often accompanied by periodontitis, which accelerates cognitive impairment induced by IH. Novel Janus mesoporous gold‐silica nanoformulations (RVG‐Au&mSiO2‐TPP‐VB) enable intranasal delivery, achieve hierarchical targeting to neuronal mitochondria, effectively scavenge reactive oxygen species, inhibit the HIF‐1α/

Higher Order Statistics-based Radial Basis Function Network for Evoked Potentials [PDF]

open access: yes, 2007
誘發電位是腦經由外界刺激,如聲音,光線,電刺激等所產反應。它們可以提供在神經徑路病變和其他神經系統診斷相關的重要資訊。然而誘發電位通常隱藏在自發性的背景腦電活動中,而且它的訊雜比非常低。如何有效地取出誘發電位仍是一項有困難性的工作。一般在臨床上總體平均法是最常被使用來取出誘發電位的方式。然而使用平均法需要大量的重複刺激來取得誘發電位,而且可能遺失掉刺激過程中每筆誘發電位間的變動差異資訊。近年來,有許多如何有效減少刺激次數來取出誘發電位的相關研究被進行探討 ...

Fixational eye movements and their associated evoked potentials during natural vision are altered in schizophrenia

open access: yesSchizophrenia Research: Cognition
Background: Visual exploration is abnormal in schizophrenia; however, few studies have investigated the physiological responses during selecting objectives in more ecological scenarios.

Sonoenzymatically Triggered Cascading Degradation of Bioresorbable Materials for On‐Demand Transient Triboelectric Implants

open access: yesAdvanced Materials, EarlyView.
Our SEA strategy provides an efficient and biosafe approach for the on‐demand removal of implanted bioresorbable materials through cascading degradation that couples ultrasound‐triggered rapid mechanical disintegration with subsequent enzymatic degradation.

Resolving Heterogeneity of Targeted Lipid Nanoparticles Through Solution‐Based Biophysical Analyses

open access: yesAdvanced Materials, EarlyView.
AF4‐UV‐DLS‐MALS‐SAXS resolves previously inaccessible targeted lipid nanoparticle (tLNP) subpopulations that differ in size, shape, and composition. Correlation of subpopulation‐resolved biophysical properties with in vivo RNA delivery reveals that targeted placental transfection is associated with distinct tLNP subpopulations rather than ensemble ...

Boolean Logic‐Based Control Over Recombinant Protein Biomaterial Degradability and Therapeutic Delivery

open access: yesAdvanced Materials, EarlyView.
Fully recombinant protein‐based biomaterials execute complex Boolean logic for user‐programmable material degradation and concomitant therapeutic cargo release. Biologics, such as growth factors, can be incorporated within the crosslinkers as “drugamers”, while encapsulated cells can be released according to nested YES/OR/AND‐type logical operations ...
