This letter presents a label-free biomolecular imaging technique based on white-light interferometry and spectral detection. The method measures thickness changes caused by specific binding between biomolecules to detect the presence of certain analyte. A
The optical properties of self-assembled InAs quantum dots (QDs) on GaAs substrate grown by metal-organic chemical vapor deposition (MOCVD) are reported. Photoluminescence (PL) measurements prove the good optical quality of InAs QDs, which are achieved us
One-step precipitation of Ag nanoparticles in Ag-doped silicate glasses was achieved through a focused picosecond laser with a high repetition rate. Absorption spectra and transmission electron microscopy (TEM) confirmed that metallic Ag nanop
