To address the declining of coral reefs, artificial reefs have been introduced to encapsulate the microalgae cells in a polymer matrix but the effects of nanoscale pollutants on these engineered systems have not been fully understood. In this work, quantum dots with a size smaller than 10 nm are being used to elucidate the photosynthesis performance of the sodium alginate beads encapsulated with Chlorella vulgaris (C. vulgaris). The fluorescent quantum dots can move into the alginate matrix and the fluorescence intensity in the algae beads is correlated with the quantum dot concentration. We further show that the photosynthesis of the algae beads is sensitive to the quantum dot concentration and are also time sensitive. In the first 48 min of quantum dot exposure, both carbon dioxide absorption and oxygen production are low, suggesting limited photosynthesis. After the initial incubation, the photosynthesis rate quickly increases even though more inhibition is still observed with higher concentration of the quantum dots. The measured electron transport rate shows a similar trend and is also sensitive to the quantum dot concentration.","is_dataset_classified":null,"base_score":2.3978952727983707,"endowment":2.3978952727983707,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21097893","pmcid":null,"openalex_id":"https://openalex.org/W4365505160","authors":[],"funders":[{"funder_name":"National Science Foundation","grant_id":"2034855","title":"Collaborative Research: Understanding \"wild-type\" nanoplastic uptake in single microalgae cells with fluorescence tracking and computational modeling"},{"funder_name":"National Science Foundation","grant_id":"2306229","title":"Collaborative Research: Understanding \"wild-type\" nanoplastic uptake in single microalgae cells with fluorescence tracking and computational modeling"}],"total_grants":2,"fwci":0.5583,"citation_percentile":0.56423538,"influential_citations":0,"citation_trend":[{"year":2023,"count":1},{"year":2024,"count":5},{"year":2025,"count":4}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.1016/j.algal.2023.103095","host_type":"journal"},{"url":"https://doi.org/10.1016/j.algal.2023.103095","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S2211926423001285?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S2211926423001285?httpAccept=text/plain","host_type":"publisher"}],"fields_of_study":["Algal biology and biofuel production","TiO2 Photocatalysis and Solar Cells","Advanced Nanomaterials in Catalysis","02 engineering and technology","0210 nano-technology"],"mesh_terms":[],"keywords":["Chlorella vulgaris","Photosynthesis","Quantum dot","Oxygen evolution","Absorption (acoustics)","Oxygen","Fluorescence","Coral reef","Nanotechnology","Materials science","Chemistry","Algae","Botany","Physics","Biology","Electrode","Ecology","Optics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life below water"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T23:19:14.880704Z","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":[]}
