“…Therefore, they concluded that the developed TCTH-Au NPs could selectively detect isoleucine with a limit of detection of 1 nm. [66] In another example, Mishra and colleagues developed a novel calix platform, resorcinarene tetrahydrazide (RTH) (19), which was then used as a reducing and stabilizing agent in the production of gold NPs. UV-visible and fluorescence spectroscopy were used to investigate the interaction behaviour of RTH-Au NPs, which had a distinctive surface plasmon resonance and were fluorescent in nature.…”

Amino acids are the most important part of the human biological system due to their role in living processes. The role of amino acids stretches beyond their traditional role as a building block for proteins, and deficiency of amino acids could lead to decreased immunity, digestive problems, depression, fertility issues, lower mental alertness, slowed growth in children, and many other health issues. The acute detection of amino acids is necessary to determine the human health domain. Here, in this review, we summarize and study the calixarenes as complexes that are of immeasurable value and their utilization for amino acid detection. Key factors such as noncovalent forces, limit of detection, and the supramolecular chemistry of calixarenes with amino acids have been well described. This study presents the most recent efforts made towards the development of potential and highly efficient calixarene-based sensors for the detection of amino acids.

“…The LSPR phenomenon is typical of non-nanostructured metal films. In the past decades, studies have proved the potential of fluorescence spectroscopy as a monitoring and detection tool in natural and engineered systems [48][49][50]. Effective control of infections may reduce the need for antibiotics and prevent rapid spread of infections globally.…”

Nanotechnology uses exceptional approaches for the control of bacterial infections which uncovers the potential function of bio-systems at nano-scale level. Compared to silver ions, silver nanoparticles possess enhanced physicochemical stability and low bio-toxicity properties. The intrinsic chemical framework of silver nanoparticles is prone to exhibit a significant chemistry when used as sensor and as therapeutic. Nowadays, silver is used in (nano-) medicine, in the form of nanoparticles to optimize its therapeutic property for controlling infections caused by multidrug-resistant bacteria. Exclusive use of antibiotics as medicines and its discharge from the body of the infected person or animals into the sewage system has led to antimicrobial resistance. Rising resistance of antibiotics is another serious threat that may lead to pandemics. Thus, there is an urgent need to develop selective and sensitive sensors for probing antibiotics, especially to prevent human health hazards. The present review emphasizes on the recent advances of silver nanoparticles concerning two inter-related subjects, first, application as a therapeutic agent to control infections and secondly, as sensors to detect antibiotics. Moreover, the chemistry of silver nanoparticles behind its applications as sensor and bactericidal agent is described. Major challenges have been elaborated for the emergence of silver nanoparticles in the field of antibiotic detection and its use for controlling bacterial infections.

“…For the same, our present study is to signify the neutral molecular recognition ability of calix [4]pyrrole tetracarboxylic acid (ABuCP) ligands. Over the last decade, our group has synthesized several calix based chemosensors [35][36][37]5] but this application can be either an extension to our effort to build up a sensor for NACs. Our goal was to use optical and more specifically colorimetric means of signalling to selectively detect nitro aromatic compounds with low concentration limits and ABuCP serves as an excellent colorimetric sensor.…”

A Novel Calix[4]pyrrole system bearing carboxylic acid functionality [ABuCP] has been synthesized and its interaction towards various nitroaromatics compounds [NACs] were investigated. ABuCP showed significant color change with 1,3-dinitro benzene (1,3-DNB) in comparison to the solution of other nitroaromatic compounds such as 2,3-dinitro toluene (2,3-DNT), 2,4-dinitro toluene (2,4-DNT), 2,6-dinitro toluene (2,6-DNT), 4-NBB (4-nitrobenzyl bromide) and 4-nitro toluene (4-NT). The ABuCP-1,3-DNB complex produces a red shift in absorption spectra based on charge transfer mediated recognition. Additionally, the density functional theory calculation confirmed the possible mechanism for the binding of 1,3-DNB as a guest is well supported by the calculation of other parameters such as hardness, stabilization energy, softness, electrophilicity index and chemical potential. The TDDFT calculation facilitates the understanding of the proper binding mechanism in reference to experimental results. Additionally we have also developed its derivative which acts as a new fluorescent sensor which can selectively recognize Sr(II) ion. In this view its aminoanthraquinone derivative of calix[4]pyrrole i.e. ABuCPTAA is synthesized which also results in generation of high fluorescence capability sensor.
