Two-layer three-dimensional DNA walker with highly integrated entropy-driven and enzyme-powered reactions for HIV detection.

Here, we propose a new two-layer three-dimensional (3-D) DNA walker sensor with highly integrated entropy-driven and enzyme-powered reactions for the first time. The 3-D DNA walker sensor is constructed by assembling densely carboxyfluorescein-labeled single strand oligonucleotides (inner-layer tracks) and nucleic acid complex S (outer-layer tracks) on a microparticle. In the presence of the target, outer and inner tracks are activated in turn, thereby releasing a great deal of the signal reporters for sign...

Smart Home Technology: A New Approach for Performance Measurements of Activities of Daily Living and Prediction of Mild Cognitive Impairment in Older Adults.

Functional assessment is of paramount importance when mild cognitive impairment is suspected, but common assessment tools such as questionnaires lack sensitivity. An alternative and innovative approach consists in using sensor technology in smart apartments during scenario-based assessments of instrumental activities of daily living (IADL). However, studies that investigate this approach are scarce and the technology used is not always transposable in healthcare settings.

A Novel 1,8-Naphthalimide-Based "Turn-on" Fluorescent Sensor for Fe.

A new fluorescent sensor was designed and synthesized from 5-nitro-1,2-dihydroacenaphthylene, n-butyl amine and 1-(2-pyridyl)piperazine. In DMF/HO (3:1, v/v), the sensor showed excellent selectivity and sensitivity to Fe with fast fluorescence enhancement and good anti-interference ability. The maximal fluorescence intensity was linearly proportional to the Fe concentration (60-140 μM). The detection limit was 81 nM. The sensor could work in a pH span of 5.0-8.0. A 1:1 complex was formed reversibly betwe...

Leveraging the Halo-Nazarov Cyclization for the Chemodivergent Assembly of Functionalized Haloindenes and Indanones.

In this report, we describe a halo-Prins/aryl halo-Nazarov cyclization strategy that employs readily available starting materials, inexpensive reagents, and convenient reaction procedures to generate functionalized haloindenes and indanones. The scope and limitations of the method are outlined, demonstrating that aromatic systems readily react under mild, catalytic conditions when this strategy is implemented. Furthermore, we present both experimental and computational data supporting the notion that cycliz...

Halo-1,2,3-triazolium salts as halogen bond donors for the activation of imines in dihydropyridinone synthesis.

In the past decade halogen bond (XB) catalysis has gained considerable attention. Halo-triazoles are known XB donors, yet few examples detail their use as catalysts. As a continuation of our previous work the catalytic properties of substituted enantiomerically pure halo-triazolium salts were explored in the reaction between an imine and Danishefsky`s diene leading to the formation of dihydropyridinones. The catalytic activity of the XB donors was highly dependent on the choice of the halogen atom and on th...

A visible chemosensor based on carbohydrazide for Fe(ii), Co(ii) and Cu(ii) in aqueous solution.

A colorimetric sensor with pyridyl and carbohydrazide components has been synthesized and visibly turns blue in the presence of Fe(ii). The colorless sensor also changes color when exposed to Co(ii) and Cu(ii), but its color becomes yellow. The sensor shows no visible response to other metal ions such Ca2+, Cr3+, Mn2+, Fe3+, Ni2+, Zn2+, Cd2+, Ag+, Hg2+, and Pb2+. The binding ratio of the sensor to Fe(ii), Co(ii), and Cu(ii) is 2 sensors to 1 metal ion. The binding constants of the sensor are: Fe(ii): 1.0 ×...

Natural polysaccharide-based smart (temperature sensing) and active (antibacterial, antioxidant and photoprotective) nanoparticles with potential application in biocompatible food coatings.

Smart and active nanoparticles are of increasing interest in food films and coatings application. In the current study, we purpose novel nanoparticles NPs-4 and NPs-4, which possess simultaneously both smart (temperature sensitive) and active (antibacterial, light absorbing and antioxidant) properties. The obtained nanoparticles are based on PEG/MC core with anthocyanidin and sodium acetate, and chitosan/gallotannin-based shell. The nanoparticles have hydrodynamic diameter ca. 450 nm and are positively ch...

Multifunctional Directional Water Transport Fabrics with Moisture Sensing Capability.

Previous fabrics with directional fluid transport capability typically have a single function to transport liquid. Multifunctional directional fluid fabrics are highly desirable for making "smart" textiles but remain a challenge to develop. In this study, we have for the first time prepared a multifunctional, directional water transport fabric. By using a two-step coating process, we applied polypyrrole (PPy), a conducting polymer, on one side of a hydrophilic fabric (cotton). We showed that the single-side...

Smart Seismic Sensing for Indoor Fall Detection, Location and Notification.

This paper presents a novel real-time smart system performing fall detection, location, and notification based on floor vibration data produced by fall downs. Only using floor vibration as the recognition source, the system incorporates a person identification through vibration produced by footsteps to inform who is the fallen person. Our approach operates in a real-time style, which means the system recognizes a fall immediately and can identify a person with only one or two footsteps. A collaborative in-n...

Optical Fiber Sensor Performance Evaluation in Soft Polyimide Film with Different Thickness Ratios.

To meet the application requirements of curvature measurement for soft biomedical robotics and flexible morphing wings of aircraft, the optical fiber Bragg grating (FBG) shape sensor for soft robots and flexible morphing wing was implemented. This optical FBG is embedded in polyimide film and then fixed in the body of a soft robot and morphing wing. However, a lack of analysis on the embedded depth of FBG sensors in polyimide film and its sensitivity greatly limits their application potential. Herein, the r...
