Biomimetic Co‐delivery of Lenvatinib and FePt Nanoparticles for Enhanced Ferroptosis/Apoptosis Treatment of Hepatocellular Carcinoma

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a novel HCC treatment using poly lactic‐co‐glycolic acid (PLGA) nanoparticles encased in HCC cell membranes to co‐deliver Lenvatinib and FePt nanoparticles. This approach improves treatment efficacy by enhancing ferroptosis and apoptosis.

Precision Photothermal Therapy at Mild Temperature: NIR‐II Imaging‐Guided, H2O2‐Responsive Stealth Nanobomb

open access: yesAdvanced Healthcare Materials, EarlyView.
The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,

Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Photoinduced optical rotation in a racemic mixture of hydrogen peroxide molecules [PDF]

open access: yesarXiv, 1999
A problem of inducing a required sign of chirality in a racemic mixture of enantiomers of a chiral molecule is analyzed. As an example, a racemic mixture (vapor) of left- and right-handed enantiomers of hydrogen peroxide (H2O2) molecule is considered. It is shown that biharmonic Raman excitation of the splitted due to the left-right conversion internal

Overoxidation of chloroplast 2-Cys peroxiredoxins: balancing toxic and signaling activities of hydrogen peroxide

open access: yesFrontiers in Plant Science, 2013
Photosynthesis, the primary source of biomass and oxygen into the biosphere, involves the transport of electrons in the presence of oxygen and, therefore, chloroplasts constitute an important source of reactive oxygen species (ROS), including hydrogen ...

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

open access: yesAdvanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential
