The performance of a very sensitive glucose sensor developed with copper nanostructure-supported nitrogen-doped carbon quantum dots.

Fluorescent glucose sensors often utilize nanotechnology to detect glucose in a sensitive and targeted manner. Nanoscale materials increase the sensitivity and efficiency of sensors by better understanding and managing the properties and interactions of the structure to be sensed. Nitrogen-doped carbon quantum dots (N-CQD), which work with the concept of fluorescence quenching or switching on because of specific processes in the presence of glucose, are one type of nanoscale material added to these sensors.

A Rare Cause of Leg Ulcer: Calcinosis Cutis as a Part of CREST Syndrome.

Leg ulcers are not a disease themselves, they are a symptom of a disease. To manage them properly, finding the correct diagnosis of the disease is mandatory. Our case is a model to underline that leg ulcers are a significant burden for the patient, because leg ulcer got ahead of the patient's other serious complaints such as Raynaud's phenomenon or sclerodactyly.
