The intersection of nanotechnology and urban agriculture: applications of carbon dots

Abstract

Amidst the ongoing urbanization process, the significance of urban agriculture has garnered increasing attention. With the expansion of urban population, the urban landscape broadens, and agriculture becomes more commercialized, the connection between the city and agriculture is gradually strengthened. Consequently, there is an urgent need to explore efficient, environmentally friendly, and sustainable modes of urban agricultural production. Carbon dots (CDs), emerging as a novel fluorescent nanomaterial, exhibit remarkable biocompatibility, nanoscale dimensions, low toxicity, and photoluminescence properties. These characteristics render CDs capable of safely and effectively enhancing photosynthesis efficiency, thus revealing immense application potential in the realm of urban agriculture. This paper delves into the characteristics and functionalities of CDs in various agricultural contexts, including plant photosynthesis, plant transport and storage systems, as well as biosecurity considerations. Furthermore, it explores the applications prospects of CDs in urban agriculture, aiming to provide robust support for the advancement of this vital sector.
