{"doi":"10.70322/gct.2025.10011","title":"Eastern Lubber Grasshopper Extract-Inspired Silver Nanoparticles Selectively Inhibit Methicillin-Resistant Staphylococcus aureus","abstract":"Silver nanoparticles (AgNPs) were synthesized using a protein/polypeptide-rich aqueous extract from the Eastern lubber grasshopper (Romalea microptera), as a natural reducing and capping agent. The resulting AgNPs exhibited relatively uniform sizes (10–60 nm) and were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet-visible (UV-Vis) spectroscopy, Transmission electron microscopy (TEM), and Scanning Electron Microscopy (SEM). Disk diffusion tests against five bacterial strains (Methicillin-resistant Staphylococcus aureus (MRSA), Burkholderia cenocepacia, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli) demonstrated that the insect-extract-induced AgNPs selectively and significantly inhibited MRSA growth, with an average value of zone of inhibition of 9.16 ± 1.11 mm (n = 4). Statistical analysis confirmed the superior antibacterial activity of the Eastern lubber grasshopper-derived AgNPs against MRSA compared to citrate-capped AgNPs and free silver ions. These findings reveal the potential of insect-derived AgNPs as selective, green-synthesized antibacterial agents with enhanced efficacy and reduced side effects, particularly against antibiotic-resistant pathogens.","journal":"Green Chemical Technology","year":2025,"id":571603,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9512,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1478004,"name":"William Joseph Dodson","orcid":null,"position":1,"is_corresponding":false},{"id":1478005,"name":"Yacoub Qamar","orcid":null,"position":2,"is_corresponding":false},{"id":1312559,"name":"William Yang","orcid":"0000-0003-0711-3414","position":3,"is_corresponding":false},{"id":1478006,"name":"Hunter Michael Salvatore Galmiche","orcid":null,"position":4,"is_corresponding":false},{"id":1477728,"name":"James Lee Cho","orcid":"0000-0003-4643-5395","position":5,"is_corresponding":false},{"id":1478003,"name":"Lauren Hanna Sloneker","orcid":null,"position":0,"is_corresponding":true}],"reference_count":26,"raw_metadata":null,"created_at":"2026-07-19T02:57:19.669553Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
