Engineered GOX nanoconstructs demonstrate remarkable tumor-specific cytotoxicity through dual mechanisms: (1) starvation via glucose deprivation and (2) oxidative damage through reactive oxygen species generation.
web_research_summary describes MMBOx as magnesium- and manganese-doped bismuth oxide with oxygen vacancies and identifies it as a named nanoparticle component in the anchor paper.
Related item candidates are limited to nanoparticle classes/components explicitly supported by the discovered literature (e.g., AgNPs, ZnO nanoparticles, CeO2 nanoparticles, MgO nanoparticles, metal nanoclusters).
The AS1411 aptamer-modified cell membrane biomimetic core-shell system is a light-augmented delivery harness for CRISPR-Cas9 plasmid cargo (pCas9). It consists of a cell membrane-camouflaged shell modified with AS1411 aptamers and photosensitizers to promote tumor targeting, reactive oxygen species-mediated lysosomal escape, and light-controllable pCas9 release for enhanced gene editing.
miniSOG is a genetically encoded protein photosensitizer described as a mini singlet oxygen generator. In the cited AR4-2J cell study, plasma-membrane-targeted miniSOG generated singlet oxygen upon light irradiation and produced photodynamic activation of cholecystokinin 1 receptor (CCK1R), leading to persistent calcium oscillations.
There are two CALI approaches that use either transgenic tags with chemical photosensitizers, or genetically encoded fluorescent protein fusions.
Chromophore-assisted laser or light inactivation (CALI) has been employed as a promising technique to achieve spatiotemporal knockdown or loss-of-function of target molecules in situ.
Low-intensity focused ultrasound (LIFU) has become increasingly used in neuromodulation.
Photochemical internalization (PCI) is a novel technology for release of endocytosed macromolecules into the cytosol. The technology is based on the use of photosensitizers located in endocytic vesicles that upon activation by light induce a release of macromolecules from their compartmentalization in endocytic vesicles.
Additional high-signal enrichment leads cluster into four useful categories: foundational CALI methodology, mechanistic papers explaining ROS-mediated inactivation, genetically encoded photosensitizer/tool-development papers (notably KillerRed, miniSOG, SuperNova), and representative application papers in neurons, mitochondria, nuclei, and whole-animal cell ablation.
TKPEI-Ce6 is a red-light-activated siRNA delivery harness built from chlorin e6-conjugated, thioketal-cross-linked polyethylenimine that condenses siRNA into nanoscale complexes. Upon 660 nm irradiation, it generates reactive oxygen species and undergoes thioketal-linked nanostructure disruption, promoting endosomal escape and cytosolic siRNA release for gene silencing.
