Nanoparticles (NPs) can be conjugated with diverse biomolecules and employed in biosensing to detect target analytes biological samples. This proven concept was primarily used during the COVID-19 pandemic gold-NP-based lateral flow assays (LFAs). Considering gold price its worldwide depletion, here we show that novel plasmonic NPs based on inexpensive metals, titanium nitride (TiN) copper covered a shell (Cu@Au), perform comparable or even better than nanoparticles. After conjugation, these...
The monoalkyl diamine surfactant, N-dodecylpropane-1,3-diamine (DPDA), is expected to exhibit a pH-dependent charge switchability. In response pH changes, the interfacial self-assembly of DPDA becomes an intermediary constituent that can potentially modify interactions and structural assembly both oil water phases. Hence, we hypothesize as change pH, will respond it by changing its alkyl tail conformation well adjacent phases at molecular level, consequently affecting emulsion formation...
This article reports the superparamagnetic behavior of metal-free nitrogen-doped graphene quantum dots (N-GQDs). The pulsed laser ablation (PLA) method was utilized to synthesize N-GQDs with an average diameter 3.45 nm and a high doping level (N/C) 1.4. Magnetic properties as-synthesized were explored by performing magnetization vs magnetic field (M–H) temperature (M–T) measurements. M–H plots measured in range 2–300 K revealed N-GQDs. value saturation found be directly correlated nitrogen...
Most photodynamic therapeutics (PDTs) used in cancer treatment require oxygen to work efficiently terminate cells. These PDTs do not treat tumors hypoxic conditions. Rh(III) polypyridyl complexes have been reported a therapeutic effect conditions when exposed UV light. light can damage tissue and cannot penetrate deep reach This proposes the coordination of BODIPY fluorophore rhodium metal center form Rh(III)-BODIPY complex that enhances reactivity under visible formation is facilitated with...
