Fluoroquinolone antibiotic residues are environmental contaminants. As these chemicals are not easily biodegradable, the development of rapid and cost-effective methods for their detection is a growing concern in the forensic industry. In a study published in Chemical analysis , Researchers have designed a microfluidic photoelectrochemical aptasensor (PEC) using photoactive AgBr/CuBi 2 HI 4 (ACO) composites for rapid and ultrasensitive detection of environmental contaminants . Study: AgBr/CuBi2O4 Photocathode Direct Z Schematic for Ultrasensitive Detection of Ciprofloxacin and Ofloxacin by Controlling Luminol Release in a Self-Powered Microfluidic Photoelectrochemical Aptasensor. Image Credit: Sonis Photography/Shutterstock.com Fluoroquinolone antibiotics, such as ofloxacin (OFL) and ciprofloxacin (CIP), pollute the environment by suppressing the activity and growth of microorganisms. This study explores a novel approach to detect ofloxacin and ciprofloxacin by controlling the r...

After an 18th round full of missing big names and late draws, this week has been made easier thanks to the return of some Fantasy guns and more certainty around the final line-up of most squads.

Winger Maika Sivo came out on a score of 48 and 53 and at $486k is pretty affordable. Broncos: Payne Haas is back after a few weeks off due to a shoulder problem. The fast returns are good news for those who hold them, but if you don’t have them, their value won’t increase much this week. Origin stars Patrick Carrigan and Kurt Capewell are also back, meaning high-scoring rookie Zac Hosking is back in the extended reserves. Tesi Niu is likely to retain the fullback position, wi...
