“…More significantly, the latest paper suggested that some silicon-containing nanomaterials are in fact not zerovalent silicon (Si 0 ) NPs. 32 Considering some previous reports indeed also indicated the absence of Si 0 , 30,33,34 the nanomaterials synthesized in this work are temporarily termed as silicon-containing nanoparticles (Si CNPs).…”

“…Despite the exciting progress in preparing Si NPs, rapid synthetic strategies under accessible mild conditions are still urgently needed . It has already been reported that Si NPs can be formed by reducing silanes in a one-step reduction process. − However, the available reductants (typically ascorbic acid, hydroquinone, glucose, or gramineae plants) are very limited; meanwhile, most synthetic processes need a long reaction time (e.g., 2 days) and/or high reaction temperature. In addition, to the best of our knowledge, almost all reports overlooked the intrinsic colorimetric properties of Si NPs and their potential application in dual-readout optical assays.…”

Alkaline Phosphatase-Triggered in Situ Formation of Silicon-Containing Nanoparticles for a Fluorometric and Colorimetric Dual-Channel Immunoassay

Enzyme-triggered in situ chromogenic and/or fluorogenic reactions under accessible conditions are significant for developing enzyme activity and related spectroscopic assays. Here, we describe a facile one-pot synthetic strategy to prepare silicon-containing nanoparticles with yellow-green fluorescence and orange-red color by mixing N-[3-(trimethoxysilyl)propyl]ethylenediamine and p-aminophenol (AP) in aqueous solution at a mild temperature. Encouraged by the AP-regulated simple synthetic procedure and the generation of AP from alkaline phosphatase (ALP)-catalyzed hydrolysis of 4-aminophenol phosphate (APP), a fluorometric and colorimetric dual-readout ALP activity assay can be rationally envisioned and developed by employing APP as the substrate. In the wake of the good analytical performance of such ALP activity assay and its successful combination with enzyme-linked immunosorbent assay (ELISA), corresponding fluorometric and colorimetric dual-readout ALP-based ELISA has been constructed for highly sensitive and quantitative determination of human prostate-specific antigen (PSA), the key biomarker of prostate cancer in human serum. The convincing performance in evaluating the PSA level in serologic tests unambiguously reveals the great potential of our proposed fluorometric and colorimetric dual-channel immunoassay in early clinical diagnosis by monitoring disease biomarkers.

Developing a single nanosensor capable of detecting multiple metal ions or biomolecules remains a challenge. Here, we successfully developed a sensing platform for the efficient detection of various metal ions with orange-emissive sulfur-doped organosilica nanodots (S-OSiNDs). The S-OSiNDs were prepared via a one-pot solvothermal treatment of urea, citric acid, and bis[3-(triethoxysilyl)propyl]tetrasulfide in N,N-dimethylformamide. The as-prepared S-OSiNDs showed a turn-off fluorescence response toward multiple metal ions including Cu2+, Fe3+, [PdCl4]2–, Ag+, Hg2+, and Bi3+, realizing the rapid and sensitive detection with a very low detection limit of 0.6 nM (for Cu2+). In addition, the metal ion-induced fluorescence quenching of S-OSiNDs could be selectively restored by glutathione (GSH), exhibiting a sensitive GSH detection capability with low detection limits ranging from 0.03 to 0.2 μM. On the basis of the metal ion/GSH-triggered on–off–on regulation of the S-OSiNDs’ fluorescence, we successfully realized the detection of Cu2+, Fe3+, [PdCl4]2–, Ag+, Hg2+, and Bi3+ and achieved cancer/normal cell identification via fluorescence microscopic imaging. Overall, the S-OSiNDs may possess great potential for the detection of multiple metal ions in environmental monitoring and clinical diagnosis, and may also serve as a robust platform for cancer cell imaging and identification because of their capacity of highly sensitive sensing of GSH, which is overexpressed in many cancer cells. Furthermore, the present work also demonstrates that S-OSiNDs can be used for the facile synthesis of metal-incorporated nanoparticles, which we believe may find various applications in the future.

“…In addition, since RC is difficult to degrade in the ecological environment, it has been recognized to be as a major pollutant in the detection of water environments by the Environmental Protection Agency (EPA) and the European Union (EU). Until now, various analytical approaches, including fluorescence, 3 colorimetry, 4 chemiluminescence, 5 and high-performance liquid chromatography, 6 have been developed for the detecting RC. Among these methods, the electrochemical approaches 7 are reliable assay methods for accurately and quantitatively monitoring RC because of their low-cost and simple operation.…”

Based on Gold Nanoparticles-l-Tyr-Amino Functionalized Mesoporous Materials-Polyphenol Oxidase Modified Biosensor for the Detection of Resorcinol

Nowadays, resorcinol (RC) has been widely applied in the chemical and pharmaceutical industries. However, the electrochemical detection technique of RC still features some significant drawbacks, for instance, a low sensitivity. Hence, in the present work, a glass carbon electrode was developed for the electrochemical detection of RC with good specificity and stability, through modifying the glass carbon electrode (GCE) by polyphenol oxidase (PPO), an NH2-SBA-15 mesoporous material (NH2-SBA-15), L-tyrosine (L-Tyr) and gold nano-particles (AuNPs). After being successively modified by AuNPs, L-Tyr, NH2-SBA-15 and PPO, the constructed PPO/NH2-SBA-15/L-Tyr/AuNPs/GCE was used to discriminate RC from ions and other common micromolecules, which showed a fairly good specificity and stability. The proposed electrochemical detection method features a linear range of from 0.5 to 21.0 μM with a LOD down to 0.15 μM, revealing a better sensitivity than the existing methods. It is worth mentioning that the proposed PPO/NH2-SBA-15/L-Tyr/ AuNPs/GCE has been successfully used as an electrochemical probe for the RC assay in domestic sewage.
