After decades of technological development, high value-added biomass-derived carbon nanomaterials with different morphologies and structures prepared by low-temperature hydrothermal carbonization (HTC) have been gradually developed into a huge system covering different series in different dimensions, and are widely used in the fields of adsorption, electrochemical energy storage, and catalysis. However, due to a vague understanding of the fundamental structure–performance correlation and the absence of customized material design strategies, the diverse needs in practical applications cannot be well met. Herein, we reviewed the mechanism, modifications, and applications of the low-temperature HTC method for biomass. The synthesis mechanisms, structural designs strategies, and related applications of biomass-derived hydrochar are highlighted and summarized in different dimensions, including six major categories: zero-dimensional spherical structure, one-dimensional fibrous and tubular structure, two-dimensional lamellar structure, three-dimensional hierarchical porous structure, and special-shaped asymmetric structure. Then a sustainability assessment is conducted on the hydrothermal carbonization process.

The surface of the Rg1 carbon nanodots is rich in hydrophilic functional groups, resulting in good dispersion in aqueous media and high biocompatibility. In Vitro experiments show that the Rg1 carbon nanodots have significant cytostatic and pro-apoptotic effects on HeLa cells, and could inhibit their migration and invasion. Experiments in tumor-bearing nude mice show that the Rg1 carbon nanodots could significantly inhibit tumor growth. Through qPCR validation, the Rg1 carbon nanodots were shown to enhance HeLa cell apoptosis, by regulating the expression levels of Cyto c, Caspase-9, Caspase-3, Bax, and Bcl-2, induce G2/M phase arrest by regulating CDK 1 and Cyclin B1 expression, and inhibit tumor cell migration by modulating CDH1 and β-catenin. Since the precursor Rg1 is a natural herbal extract, negligible toxic side effects were observed in nude mice.
