Copyright © 2019 American Chemical Society. Thermally responsive fluorescent nanoparticles can be constructed to allow robust, rapid, and noninvasive temperature measurements. Furthermore, due to their tiny size, they can be used to detect temperature changes at the nanoscale. In this way, such sensors are ideally suited to emerging applications including intracellular temperature sensing and microelectronics failure diagnostics. Despite their potential, current nanothermometers still suffer from limited sensitivity, dynamic range, and stability. By introducing thermal enhanced anti-Stokes emission from a pair of lanthanide ions, ytterbium and neodymium, we show an increase of more than 1 order of magnitude in both the sensitivity and the dynamic range when compared to conventional ytterbium and erbium-codoped nanothermometers. Here, we report heterogeneous temperature-responsive nanoparticles with a new record of sensitivity (9.6%/K at room temperature and above 2.3%/K at elevated temperatures up to 413 K) that can be used for ratiometric thermometry. The heterogeneous nanostructure design shows that the thermal responses can be fine-tuned by the controlled growth of nanoparticles. The stability of the ultrasensitive nanothermometers has enabled long-term noncontact monitoring of local heat dissipation of a microelectronic device.

Upconversion nanoparticles (UCNPs) are new optical probes for biological applications. For specific biomolecular recognition to be realized for diagnosis and imaging, the key lies in developing a stable and easy-to-use bioconjugation method for antibody modification. Current methods are not yet satisfactory regarding conjugation time, stability, and binding efficiency. Here, we report a facile and high-yield approach based on a bispecific antibody (BsAb) free of chemical reaction steps. One end of the BsAb is designed to recognize methoxy polyethylene glycol-coated UCNPs, and the other end of the BsAb is designed to recognize the cancer antigen biomarker. Through simple vortexing, BsAb-UCNP nanoprobes form within 30 min and show higher (up to 54%) association to the target than that of the traditional UCNP nanoprobes in the ELISA-like assay. We further demonstrate its successful binding to the cancer cells with high efficiency and specificity for background-free fluorescence imaging under near-infrared excitation. This method suggests a general approach broadly suitable for functionalizing a range of nanoparticles to specifically target biomolecules.

Paper-based lateral flow assays, though being low-cost and widely used for rapid in vitro diagnostics, are indicative and do not provide sufficient sensitivity for the detection and quantification of low abundant biomarkers for early stage cancer diagnosis. Here, we design a compact device to create a focused illumination spot with high irradiance, which activates a range of highly doped 50 nm upconversion nanoparticles (UCNPs) to produce orders of magnitude brighter emissions. The device employs a very low-cost laser diode, simplified excitation, and collection optics and permits a mobile phone camera to record the results. Using highly erbium ion (Er3+)-doped and thulium ion (Tm3+)-doped UCNPs as two independent reporters on two-color lateral flow strips, new records of limit of detection (LOD), 89 and 400 pg/mL, have been achieved for the ultrasensitive detection of prostate specific antigen (PSA) and ephrin type-A receptor 2 (EphA2) biomarkers, respectively, without crosstalk. The technique and device presented in this work suggests a broad scope of low-cost, rapid, and quantitative lateral flow assays in early detection of bioanalytes.

Despite significant advances toward accurate tuning of the size and shape of colloidal nanoparticles, the precise control of the surface chemistry thereof remains a grand challenge. It is desirable to conjugate functional bio-molecules onto the selected facets of nanoparticles owing to the versatile capabilities rendered by the molecules. We report here facet-selective conjugation of DNA molecules onto upconversion nanoparticles via ligand competition reaction. Different binding strengths of phosphodiester bonds and phosphate groups on DNA and the surfactant molecules allow one to create heterogeneous bio-chemistry surface for upconversion nanoparticles. The tailored surface properties lead to the formation of distinct self-assembly structures. Our findings provide insight into the interactions between biomolecules and nanoparticles, unveiling the potential of using nanoparticles as fundamental building blocks for creating self-assembled nano-architectures.

Detection and quantification of a variety of micro- and nanoscale entities, e.g. molecules, cells, and particles, are crucial components of modern biomedical research, in which biosensing platform technologies play a vital role. Confronted with the drastic global demographic changes, future biomedical research entails continuous development of new-generation biosensing platforms targeting even lower costs, more compactness, and higher throughput, sensitivity and selectivity. Among a wide choice of fundamental biosensing principles, magnetic sensing technologies enabled by magnetic field sensors and magnetic particles offer attractive advantages. The key features of a magnetic sensing format include the use of commercially available magnetic field sensing elements, e.g. magnetoresistive sensors which bear huge potential for compact integration, a magnetic field sensing mechanism which is free from interference by complex biomedical samples, and an additional degree of freedom for the on-chip handling of biochemical species rendered by magnetic labels. In this review, we highlight the historical basis, routes, recent advances and applications of magnetic biosensing platform technologies based on magnetoresistive sensors.

A novel realization of microtubular direct methanol fuel cells (µDMFC) with ultrahigh power output is reported by using "rolled-up" nanotechnology. The microtube (Pt-RuO2 -RUMT) is prepared by rolling up Ru2 O layers coated with magnetron-sputtered Pt nanoparticles (cat-NPs). The µDMFC is fabricated by embedding the tube in a fluidic cell. The footprint of per tube is as small as 1.5 × 10-4 cm2 . A power density of ≈257 mW cm-2 is obtained, which is three orders of magnitude higher than the present microsized DFMCs. Atomic layer deposition technique is applied to alleviate the methanol crossover as well as improve stability of the tube, sustaining electrolyte flow for days. A laminar flow driven mechanism is proposed, and the kinetics of the fuel oxidation depends on a linear-diffusion-controlled process. The electrocatalytic performance on anode and cathode is studied by scanning both sides of the tube wall as an ex situ working electrode, respectively. This prototype µDFMC is extremely interesting for integration with micro- and nanoelectronics systems.

Droplet-based high throughput biomolecular screening and combinatorial synthesis entail a viable indexing strategy to be developed for the identification of each microreactor. Here, we propose a novel indexing scheme based on the generation of droplet sequences on demand to form unique encoding droplet chains in fluidic networks. These codes are represented by multiunit and multilevel droplets packages, with each code unit possessing several distinct signal levels, potentially allowing large encoding capacity. For proof of concept, we use magnetic nanoparticles as the encoding material and a giant magnetoresistance (GMR) sensor-based active sorting system supplemented with an optical detector to generate and decode the sequence of one exemplar sample droplet reactor and a 4-unit quaternary magnetic code. The indexing capacity offered by 4-unit multilevel codes with this indexing strategy is estimated to exceed 104, which holds great promise for large-scale droplet-based screening and synthesis.

The first highly stretchable and sensitive spin valve sensor on elastomeric membranes are demonstrated. The sensor elements exhibit stable GMR behavior up to tensile strains of 29% in in situ stretching experiments and show no fatigue over 500 loading cycles. This remarkable stretchability is achieved by a predetermined periodic fracture mechanism that creates a meander-like pattern upon stretching.
Application fields such as smart skin1 and flexible or stretchable consumer electronics2–6 require a wide range of electronic components that are shapeable into nonplanar geometries after fabrication. Ideally, they should also be elastic and withstand many cycles of deformations without degrading in performance. Mechanical compliancy of thin films of naturally stiff materials can be achieved by different morphology transitions,6 that transfer large deformations of the substrate into small strains in the functional film, e.g., by wrinkling7, 8 or lithographically defined meander structures.9, 10 However, exploiting the full bandwidth and application potential of modern electronics requires implementation of stretchability into all types of electronic devices.
For instance, there is rapid progress in fabrication of interconnects11 and opto-electronic devices12 with stretchabilities up to several tens of percents. During the last years, magnetic13, 14 as well as magnetoresistive15–18 structures were fabricated and characterized on bendable polymeric substrates. Recently, stretchable magneto-electronics has been introduced by the fabrication of a wrinkled magnetic sensor based on [Co(Py)/Cu] multilayers19, 20 revealing a giant magnetoresistive (GMR) effect; Py stands for the permalloy, Ni81Fe19 alloy. However, only moderate stretchability of the magnetic sensor of up to about 4% was achieved. Furthermore, the sensitivity of stretchable magnetic sensors to small magnetic fields, as required for applications such as wearable electronics,1 has to be substantially enhanced....
