CdS quantum dots-based immunoassay

Full article title: CdS quantum dots-based immunoassay combined with particle imprinted polymer technology and laser ablation ICP-MS as a versatile tool for protein detection

The combination of molecularly imprinted polymer (MIP) technology with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is presented with focus on optimization of the LA-ICP-MS parameters such as laser beam diameter, laser beam fluence, and scan speed using CdS quantum dots (QDs) as a template and dopamine as a functional monomer. 

Correlative Probe and Electron Microscopy (CPEM) was used for the surface analysis allowing simultaneous acquisition of SEM and AFM images at the same place, in the same coordinate system. This combination of AFM/SEM measuring reveals surface inequalities and enables obtaining of true correlative data enabling their easier interpretation with high resolution in all 3 dimensions.
