J Fluoresc. 2019 May;29(3):609-617. doi: 10.1007/s10895-019-02373-5. Epub 2019 Apr 8.

Abstract

This study demonstrates the preparation of photosensitively orientated and crosslinked proteinous polymeric shell having quantum dot based nanocrystals through Amino acid Decorated and Light Underpinning Conjugation Approach (ANADOLUCA). ANADOLUCA is based on photo-electron transfer method and uses these decorated nanocrystals for specifically and effectively recognition and detection of Immunoglobulin M in the aqueous environment. The conjugation method effectively provides an orientation of affinity pairs on the surface of quantum dots nanocrystals. This photosensitive ruthenium-based amino acid monomer is a synthetic and inexpensive material for the preparation of bioconjugates. The nanocrystals give advantages for using a wide pH and temperature range. The construction and preparation method is applicable to silica materials, superparamagnetic particles, quantum dots, carbon nanotubes, Ag/Au nanoparticles, Au surfaces, and polymeric materials. This prepared proteinous polymeric shell decorated nanocrystals are of great potential in applications in life sciences and can be used in infection case studies or allergy symptoms.

Keywords: ANADOLUCA method; Orientated conjugation; Photosensitive crosslinking; Quantum dots; Recognition of IgM.
