The IL-Cu@Cu2O aerogels were prepared by a simple wet-chemical method using NaBH4 as reducing agent [35]. To prove that the IL was absorbed in Cu@Cu2O aerogels surface, the Fourier transform infrared (FT-IR) was performed in Fig. S1a. The peaks at 2922 and 1384 cm−1 are assigned to the CH asymmetric stretching of methylene group and CN vibration [36], indicating the successful modification of IL on Cu@Cu2O aerogels. The positively charged IL was functionalized on the surface of aerogels to

Prostate-specific antigen (PSA) is a characteristic serum biomarker for screening prostate cancer, which benefits the prostate cancer diagnosis at an early stage. At present, the reported strategies for PSA detection are mainly simplex signal readout, inevitably limiting the inherent accuracy and reliability of the involved bioassay. In this work, ionic liquid functionalized Cu@Cu2O aerogels (IL-Cu@Cu2O) with the photoelectric response and enzyme-mimicking activity are used to construct a dual-mode biosensing platform toward PSA with Ag nanopar...
