Moving photocatalyst of a titanium dioxide-based micromotor asymmetrically decorated with conjugated polymer dots

Silica-Based Platform Decorated with Conjugated Polymer Dots and Prussian Blue for Improved Photodynamic Cancer Therapy

“…The molar ratio (m:n) of PPBTBT was determined with EA and found to be 0.82:0.18 (feed ratio 0.7:0.3). PPBTBT was transformed to PPBTBT-dots by the nanoprecipitation method . The PPBTBT-dots showed UV–vis absorption at 365 and 528 nm and fluorescence emission at 650 nm, which overlapped with PB absorption (Figure a).…”

“…PPBTBT was transformed to PPBTBT-dots by the nanoprecipitation method. 48 The PPBTBT-dots showed UV−vis absorption at 365 and 528 nm and fluorescence emission at 650 nm, which overlapped with PB absorption (Figure 1a). To obtain SNP-based materials containing PB and PPBTBTdots, surface modification of SNP was performed (Scheme 2).…”

Designed a hollow Ni2P/TiO2 S-scheme heterojunction for remarkably enhanced photoelectric effect for solar energy harvesting and conversion

“…[29][30][31] However, TiO 2 can only capture and convert UV light (only 5% of solar energy), and photogenerated electrons and holes are easily recombined. [32][33][34] Therefore, to further enhance solar energy capture and the utilization of the TiO 2 , it is particularly important to properly use heterojunctions based on the hollow structures of TiO 2 .…”

Self-propelled Janus magnetic micromotors as peroxidase-like nanozyme for colorimetric detection and removal of hydroquinone

“…31,32 Among the driving modes, the self-driven micromotor, which was propelled by oxygen gas bubbles generated from the decomposition of H 2 O 2 chemical fuels due to the stable performance and active motion phenomena, has attracted great interest in recent years. 33,34 The morphology of most micromotors consists of conical microtubes, 35,36 microspheres, [37][38][39][40] nanowires 41 and other irregular structures. The traditional preparation methods of autonomously driven asymmetrical micromotors are mainly divided into four categories: vacuum magnetron sputtering, 42 template-assisted polyelectrolyte layer-by-layer assembly method 43 and lithography 44 and so on.…”
