Smartphone-based imaging colorimetric assay for monitoring the quality of curcumin in turmeric powder
Anal Sci. 2024 Apr 12. doi: 10.1007/s44211-024-00562-2. Online ahead of print.ABSTRACTThis research developed a colorimetric assay for semi-quantitative curcumin detection. The screening test was performed using a ferric chloride to form a brownish color which was further used to evaluate the amount of curcumin in the turmeric powder samples. The quantitative assay was performed based on the color intensity of the curcumin target using a smartphone digital image colorimetry with a developed lightbox constructed with a white light-emitting diodes (LED) light source as the measurement device. Images in red, green, and blue (...

Fluorescent immunoassay for chloramphenicol based on the label-free polyadenine-mediated spherical nucleic acids triggered signal amplification
Anal Sci. 2024 Apr 12. doi: 10.1007/s44211-024-00565-z. Online ahead of print.ABSTRACTA fluorescent immunosorbent assay incorporating signal amplification away from the surface of spherical nucleic acid (SNA) was developed for the detection of chloramphenicol (CAP). Through the conjugation of antibodies and poly-adenine (polyA) DNA onto the surface of gold nanoparticles (AuNPs), the fabrication of the nano-immunoprobe was achieved in a more straightforward and cost-effective manner. Moreover, a strategy utilizing the hybridization chain reaction (HCR) in the amplification step was devised, with particular attention given t...

Evaluation of the deteriorating effects of microbial primary metabolites on silk fibres
Anal Sci. 2024 Apr 12. doi: 10.1007/s44211-024-00568-w. Online ahead of print.ABSTRACTThe silk biodegradation process remains unclear and requires elucidation with advanced analytical tools. To address this challenge, the role of microbial primary metabolites in the deterioration of ancient silk was investigated using metabolomics and proteomics techniques in this work. The oxalic and palmitic acids were separately identified as the most abundant organic and fatty acid metabolites for silk-fabric deterioration via metabolomics. Proteomics showed that oxalic acid accelerated the degradation of silk proteins, revealing chang...

Bridging biological samples to functional nucleic acid biosensor applications: current enzymatic-based strategies for single-stranded DNA generation
Anal Sci. 2024 Apr 12. doi: 10.1007/s44211-024-00566-y. Online ahead of print.ABSTRACTThe escalating threat of emerging diseases, often stemming from contaminants and lethal pathogens, has precipitated a heightened demand for sophisticated diagnostic tools. Within this landscape, the functional nucleic acid (FNA) biosensor, harnessing the power of single-stranded DNA (ssDNA), has emerged as a preeminent choice for target analyte detection. However, the dependence on ssDNA has raised difficulties in realizing it in biological samples. Therefore, the production of high-quality ssDNA from biological samples is critical. This ...

Biotinylated cyclic naphthalene diimide as a searching tool for G4 sites on the genome
Anal Sci. 2024 Apr 12. doi: 10.1007/s44211-024-00551-5. Online ahead of print.ABSTRACTA biotinyl cyclic naphthalene diimide (biotinyl cNDI) (1), in which biotin is introduced on the cyclic linker chain of cNDI with high G-quadruplex (G4) specificity, was synthesized. 1 was used for binding analysis to G4 DNAs such as c-myc, c-kit, CEGF, or TA-core. The results showed that 1 bind to G4 DNAs with high affinity and, especially, two molecules of 1 bind to c-myc DNA from top and bottom of G4 site at K = 3.9 × 10-6 M-1 without changing the G4 structure. As a pulldown assay, 1 and streptavidin magnetic beads could be used to rec...
