Carrier‐Free Stimulus‐Responsive Theranostic Nanoprodrug Enabling GSH‐Consumption‐Promoted Chemo‐Photodynamic Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Leveraging the critical role of glutathione (GSH) in mediating drug resistance and scavenging reactive oxygen species (ROS) in cancer cells, a carrier‐free GSH‐consuming theranostic nanoprodrug, consisting of a BODIPY photosensitizer and the chemotherapeutic drug paclitaxel linked through a GSH‐consuming drug linker, is developed to deeply explore the ...

ANTIOXIDANT ACTION AND PHOTOSENSITIZING EFFECTS OF 3 DIFFERENT CHLORPROMAZINES

open access: yes, 1988
Chlorpromazine inhibits by about 60% the lipid peroxidation stimulated by Fe2+/ascorbate in liposomes and the lipid peroxidation stimulated by cumene hydroperoxide in microsomes. Under the same conditions, two new synthetic derivatives of chlorpromazine,

Unlocking Long‐Lived Charge‐Separated State in Pentamethine Cyanine Based on Anionic Hofmeister Effect for Photodynamic Immunotherapy

open access: yesAdvanced Science, EarlyView.
Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Detaching Photosensitive Nanoparticles from Cells Prevents Them from Remaining in Cells after Photoporation

open access: yesAdvanced Science, EarlyView.
Phenylboronic acid‐functionalized gold nanoparticles reversibly attach to cell‐surface glycans, enhancing photoporation‐mediated intracellular delivery. After irradiation, ATP competitively disrupts the boronic ester interactions and removes cell‐associated nanoparticles, markedly reducing residual gold.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

open access: yesAdvanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...
