“…Hydrogels are soft, water-based materials that are composed of three-dimensional cross-linking polymer chains. Hydrogels find applications in various fields such as biosensing, a vehicle for drug delivery, controlled drug release, and tissue engineering due to their unique properties like swelling behavior, porosity, biocompatibility, high permeability, etc. − …”

The development of a novel uncomplicated sensor for sensitive and selective detection in biomedical analysis is necessary. This study demonstrates the preparation of nitrogen-doped carbon dots (NC dots) via hydrothermal synthesis as a naked eye fluorescent probe for selective and sensitive detection of dopamine (DA). The successful synthesis of NC dots was confirmed using various microscopic and spectroscopic techniques. In addition, NC-dot-incorporated gel strips were prepared through a simple approach for naked eye detection of dopamine. The linear range for detection of dopamine was 2−20 μg/mL with a detection limit as low as 1.97 μg/mL. Moreover, NC dots showed a low toxicity toward HeLa cells, demonstrating their relevance in multicolor cell imaging. The developed probe was also utilized for quantitative determination of dopamine in a commercial pharmaceutical sample with adequate results.

Fluorescent nanocarbons are well-proficient nanomaterials because of their optical properties and surface engineering. Herein, Apium graveolens-derived carbon dots (ACDs) have been synthesized by a one-step hydrothermal process without using any surplus vigorous chemicals or ligands. ACDs were captured via an in situ gelation reaction to form a semiinterpenetrating polymer network system showing mechanical robustness, fluorescent behavior, and natural adhesivity. ACDs-reinforced hydrogels were tested against robust uniaxial stress, repeated mechanical stretching, thixotropy, low creep, and fast strain recovery, confirming their elastomeric sustainability. Moreover, the room-temperature self-healing behavior was observed for the ACDs-reinforced hydrogels, with a healing efficacy of more than 45%. Water imbibition through hydrogel surfaces was digitally monitored via "breathing" and "accelerated breathing" behaviors. The phytomedicine release from the hydrogels was tuned by the ACDs' microstructure regulatory activity, resulting in better control of the diffusion rate compared to conventional chemical hydrogels. Finally, the phytomedicine-loaded hydrogels were found to be excellent bactericidal materials eradicating more than 85% of Gram-positive and -negative bacteria. The delayed network rupturing, superstretchability, fluorescent self-healing, controlled release, and antibacterial behavior could make this material an excellent alternative to soft biomaterials and soft robotics.
