Summary: In order to enhance the antimicrobial potential of hydroxyapatite (HAp), it has been incorporated into various nanocomposites (NCs) with different structures. The HAp/tungsten oxide/graphene oxide (GO) ternary nanocomposite shows an improved cell viability of 96.7 +/-3% for osteoblast cells. Analytical techniques such as XRD, FTIR, XPS, and EDS confirm the chemical compositions. The HAp/WO3/GO composite exhibits a significant improvement in anti-microbial activity with 85.6 +/- 1.6% and 110.1 +/- 2.0% for E. coli and S. aureus, respectively.

Summary: The study demonstrated a highly efficient antibacterial nanocomposite by attaching silver nanoparticles to the surface of cetyltrimethylammonium bromide (CTAB)-loaded mesoporous silica nanoparticles. The improved antibacterial activity of the prepared nanocomposite can be attributed to the even distribution of non-aggregated silver nanoparticles per volume unit and the presence of CTAB in the nanocomposite pores.

Summary: In this study, reduced graphene oxide-amorphous carbon nanocomposites were used to fabricate graphene-based photodiodes or photodetectors, which were characterized and tested for photoresponsive characteristics.
The results showed that the photoresponsive characteristics were influenced by illumination intensity, while the electrical properties were dependent on the AC signal frequency.
Further investigation indicated that both signal frequency and density of interface states had a significant impact on the electrical characteristics of the photodiodes.

Summary: A nitric oxide-assisted PDT nanocomposite membrane was developed for significantly enhanced bactericidal performances under a single near-infrared light irradiation. The generated nitric oxide exhibited a larger sterilization area compared to reactive oxygen species, demonstrating a vital complementary advantage in facilitating PDT antibacterial efficacy as proven in in vitro and in vivo tests. This type of nanocomposite membrane may have unique biomedical applications where both highly enhanced PDT antibacterial effects and deep penetration of NIR light are desired.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
