H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Quantum probe for molecular synthesis at room temperature [PDF]

arXiv, 2004
In the present study, a prototypical reaction in biochemistry involving a well-known bio-molecule called imidazole (C3H4N2) and its known affinity towards transition metals (such as Co, Ni, Cu, Fe, etc.) has been used to illustrate and exemplify the use of ballistic conductors as probes for molecular reactions at the quantum level.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

Achieving Stable Paired Electrolysis of Captured CO2 and 5‐Hydroxymethylfurfural (HMF) via Tuning Anolyte Composition and Anode Surface

Advanced Functional Materials, EarlyView.
Highly stable paired electrolysis of CO2 and biomass‐derived alcohol (HMF) is achieved by replacing conventional alkaline electrolytes with a tailored triethylamine‐carbonate buffer and anion‐conducting ionomer coatings. This configuration effectively mitigates electrolyte degradation and pH instability typically encountered in alkaline CO2 ...
