The utilization of fluorescent quantum dots (FL QDs) has gained significant traction in the
realm of antibiotic detection, owing to their exceptional FL properties and versatility. Various …

Tetracycline (TET) residues exist in our lives and endanger our health. For rapid visual
detection of tetracycline, we designed a TET colorimetric aptasensor based on aptamer (Apt) …

Over the years, the case fatality rate of colorectal cancer is increasing. It is increasingly
important to discover new tumor markers for early diagnosis of colorectal cancer. Aptamers …

Herein, we report a Fe3O4@ polydopamine (PDA) nanocomposite and exonuclease III (Exo
