Using Density Functional Theory (DFT) and Molecular Dynamics (MD) simulations, the interactions between AA-modified graphene and the selected drugs were thoroughly investigated. Various amino acids—alanine, cysteine, glycine, tryptophan, and tyrosine—were anchored to the graphene surface, with tryptophan-modified graphene (Trp-GR) exhibiting the strongest drug binding. DFT calculations revealed that the adsorption of HU and TG onto AA-GR surfaces is exothermic and spontaneous, with Trp-GR displaying the highest adsorption energy (−31.83 kcal/mol) and the most favorable thermodynamic properties. The calculated Gibbs free energy (ΔG) values for both drugs were negative, confirming the stability of the complexes. MD simulations further demonstrated the stability and dynamic behavior of the drug–nanocarrier complexes in aqueous environments, highlighting the suitability of AA-GR as a potential drug delivery system. The results also show that Trp-GR can adsorb up to five TG molecules, with efficient and rapid drug desorption at physiological temperatures, making it an ideal candidate for controlled drug release.

Because of this, the World health organization (WHO) fixed the maximum allowed limit of Cd<sup>+2</sup> in drinking water or industrial wastewater is 3.0 µgL<sup>−1</sup>. To accurately detect even lower concentration of Cd<sup>+2</sup>, a reliable and easy-to-use method was developed by our group. Here in this work, simple and visual detection was proposed to detect Cd<sup>2+</sup> ions by using 6-Mercaptopyridine-3-carboxylic acid functionalized gold nanoparticles (MPyC-AuNPs). The prepared MPyC-AuNPs were characterized by UV–visible spectrometry, dynamic light scattering (DLS), zeta potential and Fourier transform infrared spectroscopy (FT-IR). The characteristic surface plasmon resonance (SPR) peak of MPyC-AuNPs was observed at 524 nm, and the aggregation of MPyC-AuNPs leads to spectral change from 524 nm to 677 nm. The aggregation is due to the formation of the metal ligand coordination between MPyC-AuNPs and Cd<sup>2+</sup> ions. Moreover, MPyC-AuNPs based sensor is highly selective for the detection of Cd<sup>2+</sup> and giving response only for Cd<sup>2+</sup> among tested metal ions.

The high real dielectric constant and low imaginary dielectric constant values displayed that the prepared films can be used in the manufacture of optical energy storage devices. Furthermore, the CZTS-encapsulated PAN nanofiber demonstrated notable antibacterial activity against four bacterial strains, with maximum inhibition zones (23 ± 1.25 mm) for <em>Staphylococcus aureus.</em> This makes it useful in the medical field.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"43 ","pages":"Article 101517"},"PeriodicalIF":5.45,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
