Molecular Characterization of High and Low Virulent Clinical Strains Isolated from Patients with Urinary Tract Infections with or without Bacteremia in Southern Taiwan.

Objective: The most common extraintestinal pathogen and infection site is uropathogenic (UPEC), which causes urinary tract infections (UTIs). UPEC is also a common pathogen in bloodstream infections; in severe cases, it can lead to death. Although host and bacterial virulence factors have been demonstrated to be associated with UTI pathogenesis, the role of the related contributing factors in UTI and urinary source bacteremia is not yet fully understood.

Research on a three-dimensional SERS substrate based on a CNTs/Ag@Au/SiO composite for detection of fipronil and imidacloprid pesticides.

Surface-enhanced Raman scattering (SERS) has a unique fingerprint spectrum, which allows for rapid, highly sensitive, and non-destructive detection without the need for sample pretreatment. However, SERS substrates have disadvantages such as short storage time and poor reproducibility. In this study, carbon nanotubes, gold, and silver were combined to take advantage of their inherent structural and characteristic properties that enhance the Raman effect.

Quantitative detection of phenol red by surface enhanced Raman spectroscopy based on improved GA-BP.

Phenol red (PR) is generally used as an acid-base indicator and a printing and dyeing colorant. When its content exceeds a certain concentration in water, it will cause great damage to the human body. Therefore, it is very important to detect the content of PR in water.
