Sample preparation is essential when employing chromatography for bioanalytical analysis as system performance will be negatively affected if it is not performed. Preparation methods include protein ...

X-Ray photoelectron spectroscopy (XPS) is one of the most important and widely used methods for determining surface chemistry of materials. Cryo-XPS, where the sample is cooled to temperatures below ...

Engineers designed a nanoparticle sensor that could enable early diagnosis of cancer with a simple urine test. The sensors, which can detect many cancerous proteins, could also be used to distinguish ...
