Structure and Properties of Substituted Imidazolium, Triazolium, and Tetrazolium Poly(1,2,4-triazolyl)borate Salts

open access: yes, 2007
Azolium poly(1,2,4-triazolyl)borate salts were prepared by using a simple and highly effective method. The hydrotris(1,2,4-triazolyl)borate organic salts were synthesized in high yields by metathesis reactions of Ag[HB(tz)3] with substituted imidazolium,

Spatially Configurable Conformal Sensor Integration on an Ultra‐Fine Metallic Needle for Minimally Invasive Deep‐Tissue Oxygen Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.

Vital dye reaction and granule localization in periplasm of Escherichia coli.

open access: yesPLoS ONE, 2012
BackgroundTetrazolium salts are widely used in biology as indicators of metabolic activity - hence termed vital dyes - but their reduction site is still debated despite decades of intensive research.

Tetrazolium Salt as a Seed Germination Indicator [PDF]

open access: yesAnnals of Applied Biology, 1947
A preliminary assessment of 2:3:5‐triphenyl tetrazolium chloride as a seed germination indicator has been made by testing wheat, barley, oats, peas and vetches. Results as reliable as actual germination tests have been obtained, and the optimum conditions for testing have been determined.

NONOSMIOPHILIC TETRAZOLIUM SALTS THAT YIELD OSMIOPHILIC, LIPOPHOBIC FORMAZANS FOR ULTRASTRUCTURAL LOCALIZATION OF DEHYDROGENASE ACTIVITY

open access: yes, 1972
Monotetrazolium salts were designed and prepared which incorporate a phthalhydrazide moiety to make them lipophobic and a benzothiazole moiety to make them react with osmium tetroxide after they are reduced to the corresponding formazans.

A Molecular Engineering Strategy to Fine‐Tune Phototoxicity of AIE Probes for Super‐Resolution Imaging of Mitochondrial Cristae Dynamics

open access: yesAdvanced Science, EarlyView.
Regulation of molecular packing, phototoxicity, and ROS output of AIE photosensitizers is achieved through carboxylation and alkyl‐chain‐length tuning. The probe designed via this strategy enables super‐resolution visualization of inner‐mitochondrial‐membrane cristae dynamics under controlled oxidative stress, and fluorescence‐lifetime imaging of ...

Synthesis, Characterisation and Detection of Gamma-Hydroxybutyrate Salts. [PDF]

open access: yes, 2012
Sodium, potassium, magnesium and calcium salts of gamma-hydroxybutyrate have been synthesised from gamma-butyrolactone and the corresponding group 1 or 2 hydroxide. Although the group 2 salts are non-hygroscopic, FT-IR spectroscopy and elemental analysis

Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...
