N-acetylneuraminic acid (NANA) can be used as a biomarker for many types of cancers. Currently, there are various methods for detecting NANA but showing some shortcomings that limit the real-time diagnosis of cancer. In contrast, fluorescence analysis has obvious advantages such as low cost, fast response time, and easy operation, and it also enables visual detection for real-time cancer monitoring.

Article Synopsis
- Long-term use of tetracycline hydrochloride (TC) poses environmental risks like water contamination and bacterial resistance, raising concerns for food safety.
- A new bifunctional fluorescent nanoprobe has been developed to detect two important compounds: 2,6-Pyridine dicarboxylic acid (DPA) and TC, which are significant for disease prevention and counter-terrorism.
- This nanoprobe displays enhanced red fluorescence for DPA and TC detection, achieving low detection limits (9.7 nM for DPA, 21.9 nM for TC) and allows for visual recognition of these substances through noticeable color changes.
A novel ratiometric fluorescence nanoprobe was developed to detect tryptophan enantiomers with high selectivity and sensitivity. Fluorescein (FL) was doped into SiO nanoparticles with little dye leakage, acting as an internal reference signal. The chiral center of L-histidine (L-His) was introduced by partially replacing the carboxyl on the surface of SiO.
