Self-assembly is the autonomous organization of constituents into higher order structures or assemblages and is a fundamental mechanism in biological systems. There has been an unfounded idea that self-assembly may be used in the sensing and pairing of homologous chromosomes or chromatin, including meiotic chromosome pairing, polytene chromosome formation in Diptera and transvection. Recent stu...
The selective response of supramolecular structures, cavitands, is demonstrated using a sensitive optical transduction scheme, surface plasmon resonance (SPR). The methylene bridged cavitands (MeCav) with shallow cavities do not complex aromatic vapors, the pyrazine bridged cavitands (PzCav) show intermediate selectivity whereas the quinoxaline bridged cavitands (QxCav) with the deepest cavitie...
A new macromolecule possessing two dansyl moieties and based on 2-[4-(2-aminoethylthio)butylthio]ethanamine was prepared as a fluorescent sensor and its mercury sensing properties toward various transition metal, alkali, and alkali earth ions were investigated. The designed compound exhibited pronounced Hg2+-selective ON-OFF type fluorescence switching upon binding. The new compound provided hi...
We revealed an interesting facet-dependent electrochemical behavior toward heavy metal ions (HMIs) based on their adsorption behaviors. The (111) facet of Co3O4 nanoplates has better electrochemical sensing performance than that of the (001) facet of Co3O4 nanocubes. Adsorption measurements and density-functional theory (DFT) calculations reveals that adsorption of HMIs is responsible for the d...
