Polymer shells around Ag nanoparticles were formed by two methods: the reduction of Ag(2)O in the presence of the polymer nanoparticles and by mixing the polymer nanoparticles with already-made Ag nanoparticles. The resulting nanoparticles were coated with layers of the two polymers with the hydrophilic polymer on the outside providing their stability in water. The exposure of the polymer-coated Ag nanoparticles to unmodified Ag nanoparticles resulted in spontaneous self-assembly due to the electrostatic attraction. The polymer-coated nanoparticles and the nanoparticle assemblies were characterized by UV-vis, surface-enhanced Raman scattering spectroscopy, and transmission electron microscopy.","is_dataset_classified":null,"base_score":2.833213344056216,"endowment":2.833213344056216,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19655706","pmcid":null,"openalex_id":"https://openalex.org/W2069304402","authors":[],"funders":[],"total_grants":0,"fwci":1.0865,"citation_percentile":0.76710462,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":3},{"year":2014,"count":3},{"year":2016,"count":1},{"year":2018,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/la900829z","host_type":"publisher"},{"url":"https://doi.org/10.1021/la900829z","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/19655706","host_type":"repository"}],"fields_of_study":["Gold and Silver Nanoparticles Synthesis and Applications","Polymer Surface Interaction Studies","Nanomaterials and Printing Technologies"],"mesh_terms":[],"keywords":["Polymer","Nanoparticle","Materials science","Chemical engineering","Dynamic light scattering","Polymer architecture","Transmission electron microscopy","Polymer chemistry","Nanotechnology","Chemistry","Composite material"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-11T05:34:19.776885Z","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":[]}
