Induced‐Fit Recognition by a Calixarene–Pyrene Conjugate for Single‐ and Dual‐Wavelength Fluorescence Sensing in Water

open access: yesChemistry – A European Journal, EarlyView.
A sulfonatocalix[4]arene–pyrene conjugate functions as a fluorescence chemosensor for the optical detection of biorelevant analytes in water. Its photoinduced electron transfer (PET) response is triggered by an induced‐fit recognition mechanism. Noncovalent assembly with an additional dye affords dual‐color ratiometric signaling via competitive PET ...

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

open access: yesNano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Tuning catalytic activity and sensitivity in urease‐based thin film biosensors using conjugated polymers and eugenol/biseugenol

open access: yesPolymer International, EarlyView.
Hybrid thin films of conjugated polymers and urease modified with eugenol derivatives show that polymer–biomolecule interactions enhance catalytic activity while distinctly modulating electrolyte–insulator–semiconductor sensor sensitivity. Abstract Thin films have emerged as promising platforms for biosensor development due to their versatility and ...
