“…Spectral encoding schemes incorporate mixtures of luminescent materials such as lanthanides, [10][11][12] quantum dots (QDs), [13][14][15][16][17][18] or fluorescent dyes 19,20 that emit light at different wavelengths to generate uniquely identifiable signatures. These schemes allow identification of codes in any orientation and are compatible with conventional bead synthesis procedures and standard detection optics, making them particularly attractive.…”

“…This allows obtaining a broad range of color output by single wavelength excitation using a cheap diode laser at 980 nm just by variation of dopant concentrations (Wang et al 2010 ). Even broader assortment of colors can be achieved when these particles are decorated with FRETacceptor organic dyes (Gorris et al 2011 ). In this way a large library of emission spectra in the visible and near-IR spectral region can be created that is particularly useful in multiplexed labeling.…”

“…Auf diese Weise kann der Codierungsumfang für die Mehrfachdetektion von Bioanalyten exponentiell erhçht werden. Normalerweise werden Polymermikrosphären mit organischen Fluorophoren [25] oder Quantenpunkten [26] beladen, um [90] oder von Goldnanopartikeln [91] [92] überzogen UCNPs des Typs NaYF 4 [93] Außer-dem kçnnen die Farbstoffe direkt durch sichtbares Licht angeregt werden, wie bei etablierten Codierungsstrategien, die auf Mikrosphären beruhen. [25] Somit lassen sich zwei spektrale Signaturen erzeugen: eine durch Anregung mit sichtbaren Licht und die andere durch NIR-Anregung für die Aufkonversion.…”
