Phenolic Ligand–Metal Charge Transfer Induced Copper Nanozyme with Reactive Oxygen Species-Scavenging Ability for Chronic Wound Healing
Chronic wounds frequently arise as a complication in
diabetic patients,
and their management remains a significant clinical hurdle due to
their nonhealing nature featured by heightened oxidative stress and
impaired healing cells at the wound site. Herein, we present a 2D
copper antioxidant nanozyme induced by phenolic ligand–metal
charge transfer (LMCT) to eliminate reactive oxygen species (ROS)
and facilitate the healing of chronic diabetic wounds. We found that
polyphenol ligands coordinated on the Cu3(PO4)2 nanosheets led to a strong charge transfer at the interface
and regulated the valence states of Cu. The obtained Cu nanozyme exhibited
efficient scavenging ability toward different oxidative species and
protected human cells from oxidative damage. The nanozyme enhanced
the healing of diabetic wounds by promoting re-epithelialization,
collagen deposition, angiogenesis, and immunoregulation. This work
demonstrates the LMCT-induced ROS scavenging ability on a nanointerface,
providing an alternative strategy of constructing metal-based nanozymes
for the treatment of diabetic wounds as well as other diseases
Pattern ERG responses in the Normal, Edaravone and Vehicle groups.
<p>(A) Average contrast implicit time of P50 response in the three groups. (B) Average contrast implicit time of N95 response in the three groups. (C) Average contrast amplitude of P50 response in the three groups. (D) Average contrast amplitude of N95 response in the three groups. The nonparametric Kruskal-Wallis test followed by the Mann-Whitney test was used for multiple-group comparison. Values are the means ± SD of three independent experiments.*P<0.05, ***P<0.001 vs. Normal, <sup>#</sup>P<0.05 vs. Edaravone.</p
Eeffects of edaravone on retinal ERK1/2 activation, BDNF expression and cleavage of caspase-3 in diabetic retinopathy.
<p>(A) Data are expressed as percentage change in phosphorylated ERK1/2 (p-ERK1/2) over total ERK1/2 (t-ERK1/2) (B) The histogram represents the mean band intensity of BDNF adjusted to the intensity of β-actin in the same sample. (C) The ratio of active caspase-3 (17 kDa) and pro-caspase-3 (37 kDa) was calculated in control and diabetic mice maintained with and without Edaravone treatment. Measurements were made in duplicate in six to eight mice in each group. Western blots are representative of three different experiments. Results are expressed as mean±SD. Values obtained from Normal group are considered as 100%. *P<0.05, ***P<0.001 vs. Normal, <sup>#</sup>P<0.05 vs. Edaravone.</p

Quasi-Two-Dimensional SiC and SiC<sub>2</sub>: Interaction of Silicon and Carbon at Atomic Thin Lattice Plane
The
band gap of graphene is nearly zero, and thus novel two-dimensional
(2D) semiconductor and band gap engineering of graphene is highly
desired for advanced optoelectronic applications. Herein, we have
experimentally produced quasi-two-dimensional (quasi-2D) SiC by reaction
between graphene and a silicon source, which was designed and supported
by Born–Oppenheimer molecular dynamics simulations. The lateral
length of the as-synthesized quasi-2D SiC is mainly in the range of
0.3–5 μm while the thickness is commonly below 10 nm.
Quasi-2D SiC<sub>2</sub> is also found as a byproduct, which is stable
over 3 months in air atmosphere. The exciton binding energy of quasi-2D
multilayers SiC can reach 0.23 eV while the band gap is around 3.72
eV. Additionally, in situ transmission electron microscopy has firmly
proven that quasi-2D SiC can be synthesized through the reaction between
graphene and silicon quantum dots. The first production of quasi-2D
SiC and SiC<sub>2</sub> makes the band gap engineering in the graphene
lattice plane possible
Effects of Astragaloside IV on pattern ERG outcomes.
<p>Data are expressed as the mean ± SD. A. Pattern ERG amplitudes in all groups. NC group received significantly decreased amplitudes compared with LC group (NC vs LC, p = 0.037, * p<0.05). Mice in Astragaloside IV treatment groups have increased amplitudes compared with NC group (AL, AH vs NC, p = 0.005, 0.037 respectively. ## p<0.01; # p<0.05). Amplitudes have no significance between AL and AH group. B. Pattern ERG latency in all groups. Astragaloside IV treatment changed the latency, but latency levels did not reveal a statistically significant difference.</p
