SWCNTs were individually dispersed in ethylne glycol (EG) mild bath-type sonication using quaternized poly(furfuryl methacrylate)--(2-(dimethylamino)ethyl methacrylate) p(FMA--QDMAEMA) as a dispersing agent. QDMAEMA, which has alkyl groups, was more favorable to the dispersion ability of single walled carbon nanotubes (SWCNTs). The dispersion mechanism of SWCNTs in EG helical wrapping of polymer chains along their sidewalls was suggested based on transmission electron microscopic observation.

Flexible sensors have garnered significant interest for their potential to monitor human activities and provide valuable feedback for healthcare purposes. Single-walled carbon nanotubes (SWNTs) are promising materials for these applications but suffer from issues of poor purity and solubility. Dispersing SWNTs with conjugated polymers (CPs) enhances solution processability, yet the polymer sidechains can insulate the SWNTs, limiting the sensor's operating voltage.

A bioinspired method for surface modification of nanocellulose has been proposed, drawing inspiration from the lignification process in plant cell walls. Unlike traditional methods for synthesizing dehydrogenation polymers (DHPs) of lignin, this study innovatively prepared a water-soluble DHPs precursor, coniferin, which underwent homogeneous polymerization catalyzed by peroxidase to generate DHPs that adhered to the surface of nanocellulose. Modified nanocellulose was then filtered into membranes, and the presence of DHPs increased the water contact angle, achieving high hydrophobicity with little DHPs content.

Single-walled carbon nanotubes (SWCNTs) are fluorescent materials that have been developed as sensors for measuring the activities of enzymes. However, most sensors to date rely on end-point measurement and empirical functions to correlate enzyme concentrations with fluorescence responses. Less emphasis is put on analyzing time-dependent fluorescence responses and their connections with enzymatic kinetics.

Introduction: This study aimed to evaluate the antimicrobial efficacy of single-walled carbon nanotubes when combined with the commonly used intracanal medicaments by checking their zone of inhibition against .
Materials And Methods: The test materials were divided into five different groups, namely, Group I: single-walled carbon nanotubes; Group II: calcium hydroxide; Group III: chlorhexidine; Group IV: single-walled carbon nanotubes + calcium hydroxide; and Group V: single-walled carbon nanotubes + chlorhexidine. Five sterile Petri plates per group were inoculated with (); wells were made in the plates, one on each side, and a volume of 50 microliters of each solution was dispensed into individual wells using a pipette.
