Highly stable antibacterial silver nanoparticles as selective fluorescent sensor for Fe3+ ions

Triazole Diglycolamide Cavitand for lanthanide extraction

“…Cavitand 4 was prepared by adapting a procedure described in the literature by using dichloromethane instead of bromochloromethane [27]. 4 was obtained as a white powder (yield 84%) and the 1 H NMR spectrum was in agreement with the previously reported spectrum in the literature [35,36], 1 …”

“…Among different macrocycles, cavitand analogues of C-methylcalix(4)methyl-resorcinarene provides an excellent preorganized platform for the coordination of host systems due to its conformational rigidity, which is assured by the methylene bridge between the hydroxyl groups of two neighboring phenyl rings. Its functionalization can be easily performed making the platform a focus of interest for a wide range of applications, such as being used as host molecules [20,21], components in liquid crystals [22], photoresistors [23], HPLC stationary phases [24], self-assembled capsules [25], surfactants, for potential sensor applications [26], as an antibacterial agent [27], and with biomolecules [28].…”

Thiacalix[4]arene functionalized gold nano-assembly for recognition of isoleucine in aqueous solution and its antioxidant study

“…Our group has reported synthesis of hydrazide derivatives of different calixarene platforms for the preparation of gold, silver and palladium nanoparticles [22][23][24][25][26][27][28][29][30] acids, peptides, proteins, and carbohydrate, like ultimate substrates in biological processes, by synthetic receptors is a topic of great concern from both a host-guest chemistry and analytical application point of view [31][32][33][34][35]. Naturally occurring amino acids have recently been the topic of abundant investigation due to the functional and structural prominence of such interactions in chemistry and biology.…”

Tyrosine capped silver nanoparticles: A new fluorescent sensor for the quantitative determination of copper(II) and cobalt(II) ions

“…Furthermore, amplification of light emitted from fluorophores by coupling to metal nanostructures is a promising strategy for significantly improving the detection sensitivity and hence maximizing the potential of fluorescence based technologies in bioapplications [19]. In several papers, gold and silver nanoparticles have been used as fluorescent sensors for the determination of metal ions [20][21][22][23][24], showing high sensitivity and wide linear dynamic range.…”
