Self-assembly of 1,3-alternate calix[4]arene carboxyl acids-modified silver nanoparticles for colorimetric Cu2+ sensing

Simple and rapid colorimetric sensing of Ni(II) ions in tap water based on aggregation of citrate-stabilized silver nanoparticles

“…In literature, silver nanoparticles have been functionalized in a variety of ways and used to detect different heavy metals. Nsengiyuma et al [6] have used functionalized silver nanoparticles to detect copper ions. Shrivas et al [7] also reported that they can be employed as sensor for chromium in various aqueous solutions and vegetable samples.…”

Selective Cu2+ Ion Sensing by Nanoaggregates of Pyridyl‐2,6‐bis(3‐allylsalicylaldehyde)hydrazone

“…Noticeably, the occurrence of Cu 2+ enhanced the self‐assembly process of PYAL in aqueous solution. According to the literature, self‐assembly is a thermodynamically balanced process involving the coexistence of multiple components, resulting in the formation of stable supramolecular structures ,. Therefore, the observation of several components in the ESI‐MS spectra is to be expected.…”

“…According to the literature, self-assembly is a thermodynamically balanced process involving the coexistence of multiple components, resulting in the formation of stable supramolecular structures. [21,22] Therefore, the observation of several components in the ESI-MS spectra is to be expected. The adducts formed by self-assembly will have an undefined network structure and Hbonding plus weaker interactions may be involved in the selfassembly process.…”

Functionalization of silver nanoparticles with mPEGylated luteolin for selective visual detection of Hg2+ in water sample

“…S5a, † when the concentration of Hg 2+ was in the range of 0–500 μM, the average size of mPEGylated luteolin-AgNPs increased from 77 to 170 nm, which was in good agreement with the TEM results. 21 The aggregation phenomenon resulted in changes in not only color but also instability of the mPEGylated luteolin-AgNPs. As shown in Fig.…”
