Graphene Oxide Layer-by-Layer Films for Sensors and Devices [PDF]
Layer-by-layer films of poly (allylamine hydrochloride) (PAH) and graphene oxide (GO) were characterized, looking at growth with the number of bilayers, morphology, and electrical properties. The PAH/GO films revealed a linear increase in absorbance with

Discrimination of Milks with a Multisensor System Based on Layer-by-Layer Films [PDF]
A nanostructured electrochemical bi-sensor system for the analysis of milks has been developed using the layer-by-layer technique. The non-enzymatic sensor [CHI+IL/CuPcS]2, is a layered material containing a negative film of the anionic sulfonated copper

Control of Surface Properties of Hyaluronan/Chitosan Multilayered Coatings for Tumor Cell Capture
Prostate cancer (PCa) is a slow-growing neoplasm that has, when diagnosed in its early stages, great chances of cure. During initial tumor development, current diagnostic methods fail to have the desired accuracy, thus, it is necessary to develop or ...
