: Renal lithiasis continues to represent a great challenge for modern urology in terms of minimally invasive management of lithotripsy procedures. The recent revolution of endoscopes with the miniaturization of instruments and the development of improved disposable ureteroscopes combined with recent suction methods such as suction access sheaths or direct in-scope suction (DISS) systems promise to further improve the outcome of renal stone treatment. : Considering this technological advance, this study aims to evaluate the results obtained by combining these methods in three groups: Group 1-Single-use 7.

Aflatoxin B (AFB) is a highly toxic substance found in food, necessitating rapid and sensitive detection methods. Combining interfacial capacitive sensing with AC electrothermal (ACET) enrichment, an aptasensor based on a PCB electrode array is developed for real-time detection of trace AFB. Owing to the sensitive solid-liquid capacitance with a pF-level resolution, AFB detection at sub-femtomolar level is achieved.

Novel psychoactive substances (NPS) continue to emerge in the marketplace and are often found as substances in traditional illicit drug materials, and users are often unaware of the presence of other drugs. The proper identification and confirmation of the exposure to a drug is made possible when a biological specimen is collected and tested. Sweat is an alternative biological matrix of great interest for clinical, and forensic analysis.

Lead (Pb) ion detection poses a critical problem, particularly in environmental monitoring, industrial operations, and public health, especially for young children and expecting women. Determining lead levels in blood early on is essential to minimizing the long-term consequences of lead exposure. Several sophisticated detection instruments, such as mass spectrometers which perform with high sensitivity, specificity and accuracy, but require a lab-based setting, multi-step sample preparation, expensive payment and professional operation.

Disposable biosensors provide high portability and advantageous response time, which are crucial in the next generation of analytical platforms. Herein, we report on zeolites embedding silver clusters as an electroactive material that enhances the electrode-analyte interaction in disposable electrochemical strips made of plastic or paper. The resulting analytical platform effectively immobilizes analytes and facilitates electron exchange transfer.
