Abstract:
A novel luminescent probe based on a Tb3+/Cu2+ heterometallic metal-organic framework (MOF) was first designed for beamed monitoring of urinary sarcosine, a differential metabolite that can indicate the progression of prostate cancer (PCa). The fluorescent probe presented high selectivity towards sarcosine in urine. It also displayed good sensitivity with a comparatively low detection limit and a fast response to sarcosine within 5 min. Moreover, such high selectivity and sensitivity towards sarcosine is not subject to interference from other coexisting species in urine. At the same time, this fluorescent material also demonstrated the possibility for recycling. The excellent sensing performance of this Ln-MOF (lanthanide MOF) enables it to be further employed as a serviceable tool for PCa diagnosis and monitoring.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
