“…In medicinal preparations and real body fluid, the probe exhibits excellent CIP detection capability and is highly resistant to interference. Lu et al designed a fluorescence assay for the detection of vitamin C. CoOOH could effectively quench the PL of the prepared Si NP. Due to the decomposition of CoOOH when vitamin C was added, the PL of Si NCs could recover; the principle of which is shown in Figure .…”

Due to excellent fluorescence intensity, low toxicity, good biocompatibility and stability, silicon nanocrystals (Si NCs) and Si NCs-based composites have attracted extensive attention and have been widely applied in analytical detection, biomarkers, photocatalysts, photodiodes, and solar cells. In this perspective, we summarize the recent advances in the synthesis of Si NCs and their composites and also discuss their fluorescence property and mechanism in detail. We also introduce their biological applications. Finally, the outlooks and future challenges of the promising research field are briefly discussed. This perspective is hoped to make a contribution to the subsequent synthesis and biological applications of Si NCs and their composites.

“…Evolutionary, CoOOH nanoflakes have been widely used in recent years due to their excellent water dispersion and simple and mild preparation procedure. For example, based on the fluorescence quenching effect of the CoOOH nanoflakes, the determination of ascorbic acid oxidase, ochratoxin A, ascorbic acid, T4 polynucleotide kinase activity, vitamin C, imidacloprid, and ascorbic acid has been realized. − …”

Construction of a Carbon Dots/Cobalt Oxyhydroxide Nanoflakes Biosensing Platform for Detection of Acid Phosphatase

et al. 2021

Because abnormal acid phosphatase (ACP) can disrupt the normal physiological processes, determination of ACP level is extremely important for early diagnosis, treatment, and prognostic evaluation of diseases. Herein, a fluorescence platform for monitoring ACP level was established based on the assembly of redemitting carbon dots (RCDs) on cobalt oxyhydroxide (CoOOH) nanoflakes. RCDs displayed excellent water solubility, pH stability, salt resistance, and photobleaching resistance. Interestingly, the fluorescence of the RCDs assembled on the surface of the CoOOH nanoflakes could be quenched due to the energy transfer caused by the nanoflakes. However, the ascorbic acid (AA) produced by the hydrolysis of ascorbic acid-2-phosphate trisodium salt (AAP) catalyzed by ACP could quickly and effectively reduce CoOOH nanoflakes, leading to the fluorescence recovery of the RCDs. Therefore, an "off−on" biosensor platform for rapid, sensitive, and selective detection of ACP was constructed with a limit of detection of 0.25 mU/L. With the assistance of the biosensor, the level of ACP in human serum samples was evaluated, and the spike recovery values ranged from 94.0% to 104.5%.

“…Self assembly of 2,6-pyridine dicarboxylic acid sensitised Eu 3+ and carbon dots results resometric uorescence response towards AA [22]. The blue uorescence of SiNP was quenched by CoOOH nanoparticle and on interaction with AA the later nanoparticles are decomposed by redox process restoring the uorescence of SiNP and hence falicitating sensing of AA [24]. In another method the uorescence of CD is decreased by Ag NPs produced in situ by interaction of AA with Ag(I) in presence of Ag NP seeds [25].…”

Condensation product of 5-bromosalicylaldehyde and aminophenol (L) has been synthesised and characterised. Fluorescence of L enhances by 23 times on interaction with Ce 3+ while it is quenched completely by Ce 4+ . Ascorbic acid (AA) is a well known strong reducing agent and this property has been used to act L:Ce 4+ adduct as a uorescence "on" sensor for AA. AA reduces Ce 4+ into Ce 3+ and thereby increasing uorescence of L due to the formation of L:Ce 3+ adduct. Molecules which generally coexist with AA viz. Cholesterol, Glucose, Sucrose and Dopamine found not to interfere. The interaction of L with Ce 3+ , Ce 4+ and subsequently with AA has been veri ed with cyclic voltammetry.
