The binding process of quantum dots and DNA origami was monitored using a 3D, real-time, single-particle tracking system. Single-molecule binding events were directly observed and precise measurements of the diffusion coefficient and second-order photon correlation function, g(2)(τ), were combined to distinguish free quantum dots from different conjugates of nQdot-origami.

Herein, a novel nanocomposite was developed to adjust the textural properties of metal-organic frameworks (MOFs) for adsorptive applications. To this end, nitrogen-doped carbon quantum dots/reduced graphene oxide nanocomposite (RC) was embedded into MIL-101(Cr) crystals, named RC-ML-x nanocomposites. The prepared nanoadsorbents were thoroughly characterized by different techniques.

Agro-processing industries generate a substantial quantity of biomass wastes. Conversion of these wastes into valuable material could be profitable considering both environmental and economic aspects. Among various biomass conversion methods, hydrothermal conversion can be used for co-production of biofuel and other valuable materials like carbon quantum dots (CQDs) and activated carbons.

Germanium (Ge) colloidal quantum dots (CQDs) were synthesized by thermal decomposition of GeI using capping ligand mixtures of oleylamine (OAm), octadecene (ODE), and trioctylphosphine (TOP). Average diameters could be tuned across a wide range, from 3 to 18 nm, by adjusting reactant concentrations, heating rates, and reaction temperatures. OAm promotes decomposition of GeI to Ge and serves as a weakly bound capping ligand.

In this study, a molecularly imprinted electrochemical sensor (MIECS) was constructed based on the combination of graphene quantum dots-gold nanoparticles (GQDs-AuNPs), molecular imprinting polymer (MIP), and electrochemical technology for the ultra-sensitive detection of 17β-estradiol (E). GQDs-AuNPs were synthesized and modified on the surface of glassy carbon electrodes (GCE). Safranine T was used as the functional monomer and E was the template molecule for self-assembly and electropolymerization, thus generating an MIP film on the electrode surface.

Vision loss and blindness are significant issues in both developed and developing countries. There are a wide variety of aetiologies that can cause vision loss, which are outlined in this review. Although treatment has significantly improved over time for some conditions, nearly half of all people with vision impairment are left untreated.
