However, the intrinsic instability of crRNA limits the robustness and sensitivity of CRISPR-based molecular diagnosis in practical applications. Herein, we present a simple and general enhancement strategy that suppresses RNase-mediated crRNA degradation. This strategy, termed RNase inhibitor (RI)-assisted CRISPR (RI-CRISPR), leverages RI to specifically prevent crRNA degradation, thereby improving its stability and enhancing the detection performance and anti-interference capability of the CRISPR system. Using influenza A virus (IAV) and mycobacterium tuberculosis (MTB) as model targets, RI-CRISPR improves detection sensitivity by nearly twentyfold compared to conventional CRISPR/Cas12a. Clinical validation using 40 MTB samples, combined with recombinase polymerase amplification (RPA), achieves 100% specificity and 96% sensitivity compared with the GeneXpert assay. Overall, this work provides a practical strategy to enhance sensitivity and robustness of CRISPR-based diagnostics, and is expected to promote further biomedical applications of CRISPR technology.","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"41855972","pmcid":null,"openalex_id":"https://openalex.org/W7136591784","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"82072378","title":null},{"funder_name":"National Natural Science Foundation of China","grant_id":"22504009","title":null},{"funder_name":"Chongqing Youth Science and Technology Talent Training Project","grant_id":"CQYC202005015","title":null},{"funder_name":"Chongqing Youth Science and Technology Talent Training Project","grant_id":"cstc2021ycjh-bgzxm0328","title":null},{"funder_name":"Natural Science Foundation of Chongqing Municipality","grant_id":"CSTB2025NSCQ-GPX0375","title":null},{"funder_name":"Natural Science Foundation of Chongqing Municipality","grant_id":"CSTB2025NSCQ-LZX0126","title":null},{"funder_name":"Natural Science Foundation Project of Chongqing","grant_id":"","title":null}],"total_grants":7,"fwci":7.6724,"citation_percentile":0.9698033,"influential_citations":0,"citation_trend":[{"year":2026,"count":2}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-004","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0039914026003309?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0039914026003309?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.talanta.2026.129674","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/41855972","host_type":"repository"}],"fields_of_study":["CRISPR and Genetic Engineering","Cancer-related molecular mechanisms research","Calcium signaling and nucleotide metabolism"],"mesh_terms":["Bacterial Proteins","Endodeoxyribonucleases","Humans","Mycobacterium tuberculosis","Influenza A virus","Ribonucleases","RNA, Viral","Sensitivity and Specificity","RNA Stability","Clustered Regularly Interspaced Short Palindromic Repeats","CRISPR-Cas Systems","CRISPR-Associated Proteins"],"keywords":["Enzyme","Trans-activating crRNA","Biocatalysis","Enzyme inhibition","Rnase Inhibitor","Crispr/cas12a","Crispr-Based Diagnostics","Crrna Stability"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T12:26:29.692215Z","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":[]}
