The growing use of nanomaterials and their associated risks necessitate the emergence of efficient decontamination systems. The main objective of this study is to develop a new prototype based on artificial supramolecular hydrogel capable of removing nanoparticle (NP) waste and nanomaterial by-products from aqueous suspensions. We demonstrate the high trapping efficacy of the low-molecular-weig...

This application note focuses on two challenging areas for nanoparticles: reliable, rapid scale-up of nanoparticle purification; and quantitative analysis of the concentration of species present. The Biomek 4000 Laboratory Automation Workstation helps overcome the human variable and gives a consistent, reproducible, highthroughput method for gradient setup, which provides a breakthrough for sca...

An ultra-sensitive detection strategy for prion protein is proposed based on the long range resonance energy transfer (LrRET) from quantum dots (QDs) to the surface of gold nanoparticles (AuNPs), in which process energy donor-acceptor separation distance ranges from 9 to 22 nm.

Here we report a indirect fluorescence immunoassay for high-throughput screening of APP based on the fluorescence quenching of quantum dots by gold(III), which were dissolved from gold nanoparticles-Rabbit anti-Pig IgG conjugate, and further utilize this system to detect APP in pig serum with high sensitivity and specificity.

An effective theranostic platform based on porous silica nanoparticles encapsulated with the complex of a photodynamic anticancer drug and graphene quantum dots (GQDs), with the bifunction of multicolor imaging and satisfactory photo-induced anticancer activity, was successfully designed and prepared for in vitro photodynamic therapy (PDT) of superficial cancer.

Gold nanoparticles with nanoscale protrusions can be synthesized by seed-mediated growth in favor of tuning the surface plasmon band towards the near-infrared regime. Electromagnetic field enhancement makes significant contribution to improve fluorescence emission of PbS quantum dots in the near-infrared window, identifying their application in remote imaging by collecting the scattered fluores...

For the non-invasive visualization of cell migration in deep tissues, we synthesized a short-wavelength infrared (SWIR) emitting multimodal probe that contains PbS/CdS quantum dots, rhodamine 6G and iron oxide nanoparticles. This probe enables multimodal (SWIR fluorescence/magnetic resonance) imaging of phagocyte cell migration in living mice.

This paper describes the synthesis and application of PEGylated liposome-coated quantum dots (QDs)/mesoporous silica core-shell nanoparticles (NPs) for molecular imaging. This system increases biocompatibility and stability of QDs, thus improving the imaging effects in labeling of cancer cells.
