Fluorescein isothiocyanate (FITC) functionalized Ag/SiO2/SiO2 core–shell (CS) nanoparticles (NPs) and nanorods (NRs) are synthesized by chemical method to perform the fluorescence detection of Fe³⁺ in aqueous medium. The Fe³⁺ ion sensing is performed on the basis of metal-enhanced fluorescence and subsequent fluorescence quenching of fluorophore (f...

Förster resonance energy transfer (FRET)‐based devices have been extensively researched as potential biosensors due to their highly localized responsivity. In particular, dye‐conjugated upconverting nanoparticles (UCNPs) are among the most promising FRET‐based sensor candidates. UCNPs have a multi‐modal emission profile that allows for ratiometric...

Cellulose nanofibers (CNFs) have great potential to be a layer in packaging materials because of their good barrier properties. When paper is coated with CNFs, they are difficult to distinguish from the base sheet. This issue creates challenges when trying to determine where CNFs migrate relative to the paper fibers during coating and drying. A thr...

Fluorescein isothiocyanate (FITC) is widely used to fluorescently label reactive lysine residues on proteins, including antibodies. The rate and extent of labeling varies with reaction conditions, concentration of label, and the concentration and nature of the protein. Fluorescently labeled proteins are very useful, and one use for FITC labeled mAb...

The liver is known to possess extensive regenerative capabilities, the processes and pathways of which are not fully understood. A necessary step towards a better understanding involves the analysis of regeneration on the microscopic level in the in vivo environment. We developed an evaluation method combining longitudinal imaging analysis in vivo...

Background: Piper chaba Hunt. is used as an ingredient in Thai traditional preparation for arthritis. Its isolated compound is piperine which shows anti-inflammatory activity. Piperine produces a burning sensation because it activates TRPV1 receptor. The TRPV1 activation involved with the analgesic and adjuvant effect. P. chaba Hunt. has not been...
