Development of chitosan-based adsorbents for removal of reactive Azo Dyes from Aqueous solution. [PDF]

, 2008
The adsorption of reactive blue 19 (RB19), reactive orange 16 (R016) and reactive black 5 (RB5) on cross-linked chitosan/oil palm ash composite beads was studied in batch and column modes of operation.

Fine structural tuning of diphenylaniline-based dyes for designing semiconductors relevant to dye-sensitized solar cells

Scientific Reports
Motivated by recent study on synthesized N, N-diphenylaniline (DPA)-based dyes [DOI: https://doi.org/10.1016/j.solener.2022.01.062 ] for use in dye-sensitized solar cells (DSSCs), we theoretically design several dyes and explore their potential for ...

Light‐Activatable Nitric Oxide Release via Intramolecular Electron Transfer for Tumor Pyroptosis Induction

Advanced Science, EarlyView.
This work proposes a novel strategy to fabricate unimolecular pyroptosis photoinitiators activated by deep‐red light at low light doses. It relies on a photosensitization mechanism to trigger nitric oxide (NO) release from benzisothiadiazole‐based N‐nitrosanilines without modification of nitro moieties, thereby boosting pyroptosis‐mediated ...

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

Advanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

Catalytic degradation of diverse azo dyes using Eucommia ulmoides bark-mediated gold nanocatalyst

Environmental Chemistry and Ecotoxicology
In the absence of any hazardous substances, colloidal gold nanoparticles (AuNPs) were synthesized through the reduction and stabilization of corresponding metal cations by a simple Eucommia ulmoides bark extract (EUBE). Employing these AuNPs as catalysts,

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Removal of azo dyes from aqueous solutions using calix[4]arene and beta-cyclodextrin

, 2007
A calix[4]arene-based oligomer 5 and a P-cyclodextrin polymer 6 were synthesized by the condensation of p-tert-butylcalix[4]arene and beta-cyclodextrin, respectively, with hexamethylene diisocyanate. In their batch sorption of selected azo dyes, the beta-

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, EarlyView.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.
