尹教授長期以來圍繞“熒光拓撲高分子材料的構建與功能化”這一高分子材料領域的重要前沿課題，開展了熒光功能高分子的設計/合成以及生物應用的系統研究。熒光小分子化合物一般具有疏水的共軛結構，在生物或極性介質中容易聚集，導致熒光衰減或猝滅。此外，傳統高分子載體不含有熒光基團，很難在細胞內起到標記、示蹤的作用。因此，需要解決的關鍵科學問題是既要確保熒光分子具有水溶性、光穩定性，又要賦予熒光分子一定的生物相容性、特異功能性。針對以上關鍵問題，尹梅貞教授將熒光發色基團與拓撲功能高分子有機結合起來，提出了將拓撲功能高分子作為外圍殼保護和隔離疏水熒光核的新策略，構建了系列核-殼熒光拓撲高分子材料，解決了水溶性與光穩定性差的難題。在此基礎上，發明了新型熒光抗癌藥物分子以及多種特異性熒光分子探針，使其具有“熒光示蹤”和“納米載體”雙功能 ，開創性地建立了將熒光納米載體用于農業害蟲防治新技術，成功地攜帶基 因/藥物/蛋白應用于農作物害蟲綠色防控等，為避免化學農藥的過度使用打開了綠色生物防治新思路。研究工作帶動了熒光標記以及抗腫瘤研究領域的 發展，引領化學與生命醫學以及農業交叉學科研究，具有重要的學術價值以及實際應用前景。例如，美國國立研究院Nard Kubben研究員，美國約翰霍 普金斯大學Jan H. Hoh教授，以及德國美因茨大學Gert O. Pflugfelder教 授，采用尹教授團隊構建的熒光分子用于他們的生物學示蹤等生命科學研究 。安貞醫院心血管重大疾病協同創新中心（2011協同創新中心）杜杰教授團隊使用尹教授團隊的熒光抗癌藥物分子進行癌癥早期診斷研究。中國農業大學，華南農業大學等農業高校研究人員使用尹教授提供的熒光高分子材料從事他們各自領域的不同種類昆蟲遺傳學等研究。
