“…Likewise, 11-mercaptoundecanoic acid (MUDA) conjugated GNPs have been reported for binding to specific antibody molecules [42]. Maleic acid functionalized GNPs are used for detection of Pb 2+ ions [43].…”

“…Control sets treated with other metal cations yielded a negative result suggesting high affinity of GSH to bind to Pb 2+ ions. Lately, maleic acid [106] and calixarene functionalized gold nanoparticles (CFAuNPs) [96] have been reported to assist in Pb 2+ ions detection. In the former case, Pb 2+ ions bind to the free -COOH groups of maleic acid [106].…”

In the former case, Pb 2+ ions bind to the free -COOH groups of maleic acid [106]. Both the cases were based on metal induced aggregation of nanoparticles that results in interparticle plasmon coupling and resultant change in colour and red shift of SPR peaks [106,96].…”

“…Maleic acid (dicarboxylic) functionalized with gold nanoparticles is used in the colorimetric detection of high efficiency of lead [131]; correspondingly, copper nanoparticles functionalized with carboxylic acid act as catalysts, when reducing 2-nitrophenol to 2-aminophenol in a few minutes [132]. Hence, it can be concluded that the different applications of metallic and nonmetallic nanoparticles in combination with organic agents such as carboxylic groups are of great importance in future medical applications for the development of antineoplastic therapies.…”

The technological and biomedical applications of low toxicity and eco-friendly organic compounds are nowadays increasingly attracting the attention of researchers in nanoscience, who are aiming for more biocompatible and nanostructured systems for their application in antineoplastic therapies. This study presents the significance of "green components" in the production of graphene, metallic, and semiconductor nanoparticles, due to their antioxidant and antitumor properties. The formation of nanostructures is caused during green synthesis methods by organic molecules or carboxylic acid groups present in some plant extracts; for this reason, we include here a recapitulation and analysis of the role of carboxylic acids in those systems (organic). Furthermore, we propose the use of the extract from Opuntia ficus-indica cladodes to obtain metallic and carbon nanostructures, as an alternative biosynthesis method for the development of future nanobiotechnological applications.
