Abstract
Quantum dot-encoded beads as a new type of fluorescent labels exhibit significant advantages over common organic dyes, such as narrow, strong and tunable emissions, excellent photostability, good versatility in structure and component, and simplicity for excitation of multiple nanocrystals. These features lead to the great potential of the beads in the fields of ultrasensitive detections, clinical diagnostics, as well as molecular imaging. This report will briefly review the fabrication and optical properties of the beads based on recent papers and patents. The applications of the beads in ultrasensitive detections are also discussed. The systematic introduction from basic studies to practical applications would give us a comprehensive and clear view about this field, disclose the current challenges, and promote their future developments.
Keywords: Quantum dot, barcodes, preparation, optical properties, molecules detection

Green Nanotechnology and Nanomaterials for a Sustainable Environment
Green nanotechnology (GN) might wind up being the most efficient platform for achieving the goals of the 2030 Agenda. The goal of GN is to create goods and procedures that are secure, energy-efficient, waste-free, and emit fewer greenhouse gases. Such goods and procedures use renewable resources, and/or their environmental impact ...read more
Nano-coatings and Nanoscale Composites for Hazardous Environments
Automobile, defence, and aerospace sectors need lightweight material for fuel efficiency and lower emissions. Often these materials are added with nanoscale reinforcements or have to be coated with nanomaterials to improve the scratch resistance, self-healing behaviour and corrosion and wear resistance and are all much needed for hazardous environments without ...read more
