• Nose-to-brain transport of aerosolised quantum dots following acute exposure.

• Hopkins LE, Patchin ES, Chiu PL, Brandenberger C, Smiley-Jewell S, Pinkerton KE.Author information Center for Health and the Environment, University of California , Davis, CA , USA.AbstractAbstract Nanoparticles are of wide interest due to their potential use for diverse commercial applications. Quantum dots (QDs) are semiconductor nanocrystals possessing unique optical and electrical properties. Although QDs are commonly made of cadmium, a metal known to have neurological effects, potential transport of QDs directly to the brain has not been assessed. This study evaluated whether QDs (CdSe/ZnS nanocrystals) could be transported from the olfactory tract to the brain via inhalation. Adult C57BL/6 mice were exposed to an aerosol of QDs for 1 h via nasal inhalation, and nanoparticles were detected 3 h post-exposure within the olfactory tract and olfactory bulb by a wide range of techniques, including visualisation via fluorescent and transmission electron microscopy. We conclude that, following short-term inhalation of solid QD nanoparticles, there is rapid olfactory uptake and axonal transport to the brain/olfactory bulb with observed activation of microglial cells, indicating a pro-inflammatory response. To our knowledge, this is the first study to clearly demonstrate that QDs can be rapidly transported from the nose to the brain by olfactory uptake via axonal transport following inhalation.

• A nanosensor based on quantum-dot haptens for rapid, on-site immunoassay of cyanotoxin in environmental water.

• Feng L, Zhu A, Wang H, Shi H.Author information School of Environment and Natural Resources, Renmin University of China, Haidian, Beijing 100872, China; School of Environment, Tsinghua University, Haidian, Beijing 100084, China. Electronic address: longf04@ruc.edu.cn.AbstractA nanoprobe based on quantum-dot (QD) haptens was synthesized by conjugating carboxyl quantum dots with aminoethyl-microcystin (MC)-leucine-arginine (LR). A two-alkyl group was introduced to supply a spacer between the QD nanoprobe and anti-MC-LR antibody to reduce the steric hindrances of immunoreaction. The sensor system based on a portable optofluidic platform exhibited a liner range of 0.10-4.0µg/L for MC-LR with a detection limit of 0.03µg/L. The proposed sensor has potential application in the rapid, on-site detection of MC-LR in real water samples.

• Cyclic GMP recognition using ratiometric QD-fluorophore conjugate nanosensors.

• Cywinski PJ, Moro AJ, Löhmannsröben HG.Author information Physical Chemistry, Department of Chemistry, University of Potsdam, Karl-Liebknecht-Strasse 24-25, 14476 Potsdam-Golm, Germany. Electronic address: piotr.cywinski@iap.fraunhofer.de.AbstractNovel luminescent ratiometric nanosensors (QD-NAPTHs) were prepared based on cadmium telluride (CdTe655) quantum dots as luminescent nanoscaffolds with naphthyridine dyes as fluorescent receptors. This biosensing bifluorophoric nanosystem has been designed to achieve detection of guanosine 3',5'-cyclic monophosphate (cyclic GMP) in buffered media. Cyclic GMP is a secondary messenger that is an important factor for detecting cancer, diabetes and, cardiovascular diseases. Due to low concentration levels, even in pathological conditions, sensitive cGMP detection remains a challenge for modern biomedical diagnostics. Here, QD-NAPTH nanosensors were tested in the presence of a target nucleotide and with various structural cGMP analogues. Steady-state fluorescence spectroscopy was used to monitor a change in the nucleotide concentration. A 5-fold increase in naphthyridine fluorescence with a simultaneous decrease in QD luminescence was observed after adding 50 μM of cGMP. Using this novel nanosystem with ratiometric detection, it was possible to recognize cGMP with limit of detection (3σ) equal to 70 ng/ml. Moreover, the enhancement in fluorescence upon interaction with the target nucleotide constitutes a favourable approach towards the detection of cGMP in buffered media. These bifluorophoric nanosensors have a potential for application in fluorescence microscopy imaging and in-vitro assays.
