Generation of hydroxyl radicals during photodegradation of chloroacetic acids by 254 nm ultraviolet: A special degradation process revealed by a holistic radical determination methodology

Lei Wang et al.

Summary: This study showed that reduced oxygen mainly generates center dot OH, and photolysis products can trigger the formation of H2O2 under 254 nm UV. Additionally, evidence of direct photolysis-induced indirect photolysis phenomenon was presented, along with a comprehensive methodology to identify the presence and sources of radicals.

Triapine/Ce6-loaded and lactose-decorated nanomicelles provide an effective chemo-photodynamic therapy for hepatocellular carcinoma through a reactive oxygen species-boosting and ferroptosis-inducing mechanism

Pengfei Zhang et al.

Summary: This study presents a nanomicelles-based and lactose-decorated drug delivery system (DDS) loaded with Triapine and Ce6 for combined chemo-photodynamic therapy (CT-PDT) against hepatocellular carcinoma (HCC). The system shows a highly hepatocyte-targeted delivery and enhanced anticancer activity, with Triapine inducing ferroptosis and PDT enhancing ferroptosis mediated by singlet oxygen. In vivo, the tumor-retarding ability of the system outperforms Triapine, demonstrating the potential of nanomaterials-based DDS for cancer therapy.

Preparation and properties of a dual-function cellulose nanofiber-based bionic biosensor for detecting silver ions and acetylcholinesterase

Lei Wang et al.

Summary: A dual-function cellulose nanofiber (CNF)-based bionic biosensor has been developed for detecting Ag+ and acetylcholinesterase (AChE) with high sensitivity and selectivity, by grafting DNA onto CNF and forming DNA-template silver nanoclusters (DNA-AgNCs) without using additional reducer. This new strategy may pave the way for further research in developing biosensors and biomarkers for in vivo and in vitro detection.

Hydrophobic modifications of hydroxyethyl cellulose polymers: Their influence on the acute toxicity to aquatic biota

Anabela M. Simoes et al.

Summary: The study investigates the influence of hydrophobic substitution on the acute ecotoxicity of quaternized hydroxyethyl cellulose polymers to aquatic biota. Results show that compounds with lower hydrophobic substitution exhibit lower ecotoxicity, and certain species such as Raphidocelis subcapitata, Chlorella vulgaris, and Brachionus calyciflorus are most sensitive to these substances, potentially disrupting lower trophic levels.
