Surface‐defective GOQD C‐GQD out facilitate uptake through leaf stomata, seedlings of differently ages various degrees at different concentrations after durations exposure. Specially, compared the ddH 2 O treatment, GOQD/C‐GQD 400 mg L −1 increase biomass by 44%/68%, chlorophyll content 43%/54% up‐regulate expression growth‐related genes NtLRX1 , CycB NtPIP1 more than two‐fold.

Abstract Photosynthesis has garnered significant interest due to its potential for retrofitting and intrinsic enzyme‐mediated metabolic processes, which can convert carbon dioxide (CO 2 ) into biomass powered by solar energy. However, natural photosynthesis is limited factors such as low photosynthetic efficiency constraints on the range of output products. To address these issues, researchers have developed various strategies designing engineering systems. These include nanomaterial‐assisted approaches enhance light absorption accelerate electron transfer, microfluidic technologies precise manipulation enzyme modules, synthetic biology techniques optimize pathways, photo‐bioelectrochemical systems (PBESs) efficient utilization electrons. Inspired these, numerous applications emerged in fields artificial organelles, promotion hypoxic tissue healing, bioproduction, environmental production sustainability. This review provides a comprehensive introduction principles photosynthesis, encompassing reactions. Additionally, it offers an overview recent design, structuring, systems, while discussing several photosynthesis. Finally, this highlights engineered challenges energy matter conversion across fields, offering insights future sustainable, photosynthesis‐based technologies.
