“…The gold nanoparticles used in this study display a surface plasmon (SP) resonance band at about 520 nm (Figure 1), the shift of which is correlated to the change in the size, interparticle distance, and dielectric medium [28][29][30][31][32]. As shown in Figure 1(a), the solution of the DNA capped nanoparticles (A1 + A2) (red solution) exhibited an SP band at 525 nm.…”

This report describes the viability of a strategy for manipulating the assembly/disassembly processes of DNA-Au nanoparticles by molecular intervention. Using the temperature-induced assembly and disassembly processes of DNAs and gold nanoparticles as a model system, the introduction of a molecular recognition probe is demonstrated to lead to the intervention of the assembly/disassembly processes depending on its specific biorecognition. This process can be detected by monitoring the change in the optical properties of gold nanoparticles and their DNA assemblies. Implications of the preliminary results to exploration of the resulting nanostructures for fine-tuning of the interfacial reactivities in DNA-based bioassays and biomaterial engineering are also discussed.

The present review deals with the preparation and the properties of star-shaped conjugated compounds. Three, four or six conjugated arms are attached to cross-conjugated cores, which consist of single atoms (B, C+, N), benzene or azine rings or polycyclic ring systems, as for example triphenylene or tristriazolotriazine. Many of these shape-persistent [n]star compounds tend to π-stacking and self-organization, and exhibit interesting properties in materials science: Linear and non-linear optics, electrical conductivity, electroluminescence, formation of liquid crystalline phases, etc.

“…The membrane paper features an extremely high surface to volume ratio and nanofiltration capability. With metal nanoparticles, which are widely exploited as sensing or biosensing materials, different molecules or biomolecules have been utilized as interparticle linkers ranging from alkyl dithiols or functionalized thiols to polymers or biopolymers . In comparison to traditional linkers, dendrimers represent a class of macromolecules with well‐defined 3D branched structure exhibiting a high degree of functionality and versatility.…”

The development of wearable breath or sweat sensor arrays for human performance monitoring is increasingly important for providing personalized health information under various environmental conditions. A major challenge is the lack of sensing elements responsive uniquely to moisture‐dominated breathing and sweating processes, which is critical for differentiating other chemical or biological species from the moisture‐dominated environment. Here a novel class of nanofibrous paper chemiresistors decorated with dendronized nanoparticles that exhibit structurally tunable and negative‐going responses to human breathing and sweating is reported. The nanocomposite device features flexible membrane‐type scaffold derived from multilayered nanofibrous paper as a biocompatible matrix and dendronized gold nanoparticles with tunable sizes and shapes to enable structural diversity and molecular sensitivity. Key elements of novelty include the immobilization of poly(ether‐ester) dendrons with oligoethylene glycol spacers on gold nanoparticles and the combination of hydrogen bonding and van der Waals interactions between partially interpenetrating dendrons, leading to tunable and unique response characteristics to breathing and sweating processes. The results demonstrate the first example of nanofibrous paper chemiresistors decorated with dendronized nanoparticles as a promising new strategy toward constructing sensing interfaces for wearable breath and sweat sensors.
