“…12). 105 It was revealed that the selective binding of As( iii ) with 80 among various other competing anions (Cl − , NO 3 − , SO 4 2− , and PO 4 3− ) on the surface of Au-NPs resulted in a visible color change from pink to blue, and also a red shift in the absorbance, as revealed by UV-Vis spectroscopy. The aggregation of the C4P ( 80 )-fabricated Au-NPs upon the colorimetric sensing of As( iii ) is owing to the existence of non-covalent interactions between C4P ( 80 ) and As( iii ) (Fig.…”

“…[47] Cytotoxicity results expressed (Table 1) are the optical density at 570 nm and % cell inhibition as compared to control (Figure 9 (a), (b)). The IC 50 value (half minimal inhibitory concentration) was taken as the factor for cytotoxic nature of CPTAH-AuNPs in contrast to control Doxorubicin and was [49] For good measure, the calix[4]pyrrole stabilized MCPTH-AuNPs obtained the IC 50 value to be 25.69 μg/mL, [34] other calix [6]rene and ChemistrySelect calix [8]rene stabilized AuNPs were reported the LD 50 values to be 21.37 μg/mL & 66.72 μg/mL for brine shrimp lethality assays.

“…for the surface functionalization of gold nanoparticles served for sensing of cobalt (II) ions, [29] and another by Kongor et al. for the effective use of calix[4]pyrrole gold nanoparticles for the detection of harmful arsenic (III) ions [34] focused on an exclusive application of calix[4]pyrrole. To expand upon the ability of calixpyrrole to functionalize the surface of gold, the novel compound calix[4]pyrrole tetraacetohydrazide (CPTAH) has been employed in the present investigation to prepare the extremely stable CPTAH‐AuNPs, which were used, for colorimetric and fluorimetric sensing of the fungicide dimoxystrobin (DMX) and its anti‐cancer activity against human cancer cell line KB‐3‐1 as far as we are aware, for the first time.…”

A rapid and easy approach for producing very stable gold nanoparticles has been discovered. Calix[4]pyrrole tetrahydrazide (CPTAH) was utilized effectively in the synthesis of gold nanoparticles as a reducing and stabilizing agent. These functionalized AuNPs were characterized by Surface Plasmon Resonance, Transmission Electron Microscopy, Selected Area Electron Diffraction, and Energy Dispersive X‐ray techniques. CPTAH‐AuNPs possessed a particle size of 11±2 nm and are highly stable at pH 7.0 for more than 150 days. The selectivity and sensitivity of CPTAH‐AuNPs as a fungicide sensor was assessed for Metalaxyl, Mancozeb, Tebuconazole, Tricyclozole, Dimoxystrobin, Kresoxim‐methyl, and Carbendazim, amongst which Dimoxystrobin (DMX) was sensed exclusively with naked eyes by means of aggregation of CPTAH‐AuNPs with a detection limit of the order of 5 ppm using “Turn‐on” fluorescence enhancement. Additionally, the CPTAH‐AuNPs were found to be effective cytotoxic agent against the human cervix cancer cell line KB‐3‐1 with IC50 value of 64.63 μg/mL which admits the employability of CPTAH‐AuNPs in the study of development of anti‐cancer drug.

The emergence of plasmonic nanostars with their attractive properties and unique versatility has enabled a wide range of advanced technologies critical to human health, safety, energy, and environmental remediation with vast potential for further exploration. In addition to their superior surface-to-volume ratios compared to those of other plasmonic nanostructures, plasmonic nanostars arguably possess the largest numbers of hotspots with intensely amplified electric fields when they are subjected to suitable electromagnetic waves to trigger localized surface plasmon resonance (LSPR). These outstanding characteristics make plasmonic nanostars ideal for many applications that benefit from the plasmonic enhancement effect of LSPR and/or the large surface area. Over the past decade, an increasing number of research endeavors has been reported on the synthesis and application of plasmonic nanostars to advance the state-of-the-art for various existing technologies. These contributions are pertinent to real-time image-guided multifunctional anticancer theranostics, the ultrasensitive on-site detection of the devastating virus SARS-CoV-2, multimodal multiplexed brain imaging, greatly enhanced catalysts for energy and environmental processes, or more efficient and stable solar cells. In addition to the enhancement of important but familiar technologies, plasmonic nanostars have also been employed to push the technological frontiers in multiple fields to enable applications such as maskless write-on lithography, nanosized field electron emitters, coherent random lasers, neural activity modulation, and optically controlled electrical currents. Despite great performance in various fields since their introduction, the nascency of this unique class of plasmonic nanostructures and the rise of unique types of plasmonic nanostars, in addition to the dominance of gold nanostars in recent years, indicate that there are still many opportunities for study, exploration, and development. This Review outlines a comprehensive picture of the current state of plasmonic nanostar research with a focus on their technological and scientific applications. We hope this Review will enlighten future collective endeavors to develop more effective plasmonic nanostars and incorporate them into mainstream technologies so that these stars can truly shine.
