| 1 | Superwettable interface towards biodetection in confined space显示文摘The detection of biomarkers with both high sensitivity and specificity is crucial for the diagnosis and treatment of related diseases.However,many current detections employ ex-situ detection method and non-confined condition,thus have many problems,which may eventually lead to inaccurate detection results.Compared to detection in non-confined space,detection in confined space can better reflect the real in-vivo situation.Therefore,the construction of detection for target molecules in confined space has great significance for both theoretical research and practical application.To realize the detection of target molecules in confined space,the probes should accurately enter the confined space where the target molecules reside and interact with the interface.Thus,how to explore and utilize the properties of the interface(for example,bioinspired superwettability)has always been a hot and difficult topic in this field.Herein,the recent advances and our efforts in recent 10 years on detection of bio-target molecules in confined space with superwettable interface have been introduced from the perspective of the detection methods.The suitable and most widely employed detection methods for target molecules in confined spaces are introduced firstly.Then,recent progresses for related detections based on visual,optical,and electrochemical detection methods are presented successively.Finally,the perspective for detection in confined space is discussed for the future development of biochemical detection. | Zexu Pang Zhikang Cao Wanlu Li Wenxia Xu Yingying Zhang Qitao Zhou Jing Pan Fan Xia | 2024 | Nano Research2024，17，2： | 1 |
| 2 | PCE10显著提升三元倍增型有机光电探测器红光与近红外光探测能力显示文摘近红外光探测能力强的光电探测器更有利于检测人体心率,而且探测范围覆盖红光与近红外光的宽带响应光电探测器能用于检测血氧饱和度,因此提升宽带响应光电探测器的红光与近红外光探测能力具有重要意义。然而,经典的二元体异质结宽带响应倍增型有机光电探测器通常由于活性层中给体/受体比例差异较大,导致器件对红光与近红外光的响应能力较弱甚至没有响应。本文通过用少量给体材料PCE10替代活性层P3HT∶IEICO‐4F(100∶1)中部分P3HT的方法,制备了结构为ITO/PEDOT∶PSS/P3HT∶PCE10∶IEICO‐4F(90∶10∶1)/Al的体异质结三元倍增型有机光电探测器。-20 V偏压下,三元器件获得紫外到近红外(330~810 nm)响应较均匀的EQE光谱,并且器件在660 nm和810 nm处的EQEs(134000%和147000%)是相同条件下二元器件的78倍和106倍,相应的探测灵敏度(5.4×10^(13)Jones和7.27×10^(13)Jones)分别提升了26倍和36倍。三元器件的红光和近红外光探测能力得到显著提升,为制备用于人体心率与血氧饱和度检测的高性能光电探测器提供了策略。 | 王建彬 唐孝生 周笔 曾夏辉 黎金城 周赢武 | 2023 | 发光学报2023，44，12： | 0 |
