A series of rhodol-; fluorescein- and rhodamines-based spirolactam compounds, bearing electron donor amines have been prepared. For this purpose we have redesigned the synthesis of the rhodol scaffold using 2-(2,4-dihydroxybenzoyl)benzoic acid obtaining one example rhodol methyl ester in good yields (25-30 %) Thus, one set of non-cytotoxic rhodamine-based compounds has been prepared using thermal and microwave assisted synthesis (40-78 %) and tested as high affinity ATP chemo-sensors.

Implant-related infections (IRIs) pose a major challenge in orthopedic applications due to the persistence of biofilms, which are highly resistant to conventional antibiotics. This study introduces oxygen vacancy-engineered Zn-Fe spinel nanoparticles as microwave-responsive antibacterial agents. The oxygen vacancies in the spinel structure enhance reactive oxygen species (ROS) generation under microwave irradiation, providing a dual-mode antibacterial mechanism of thermal and oxidative stress.

Carbon dots (CDs) have emerged as promising nanomaterials for bioimaging and stress monitoring due to their unique optical and functional properties. CDs were synthesized using citric acid and -phenylenediamine via microwave-assisted heating, named as CP-CDs. High-resolution transmission electron microscopy observed an average particle size of 3.

The current research involves the preparation of novel thiazole derivatives, which was carried out via one-pot three-component reaction utilizing conventional and microwave irradiation (MW) methods. The MW method reduced the reaction time and allowed the reactions to be carried out with higher yields. 1H NMR, 13C NMR, EI-MS and FT-IR techniques were employed for the characterization of synthesized compounds.

The surface charge of carbon dots (CDs) governs cellular uptake; however, studies seldom compare CDs with similar physico-chemical properties thereby introducing confounding variables. Here, we investigate how the surface charge of amine-passivated carbon dots with similar optical and chemical properties influences their uptake in human cells. We synthesized CDs using citric acid diethylenetriamine (DT3) or pentaethylenehexamine (PH6) using microwave-assisted synthesis.

MFeO (M = Co and Mn) nanoparticles were synthesized from coconut coir extract using a microwave-assisted co-precipitation method, representing a green and sustainable approach for ferrite nanomaterial preparation. The physical properties of the samples were characterized using X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, photoluminescence, Raman spectroscopy, and vibrating sample magnetometry. Scanning electron micrographs revealed nanoscale morphology with evidence of polymorphism.
