Hexavalent chromium is a toxic environmental pollutant that damages plants due to disruption of nutrient uptake, photosynthesis metabolism, and oxidative stress, which suppresses the growth and development of the plant. In this work, we have developed a betaine-modified carbon dot (BT@CD) sensor for monitoring Cr(VI) in water and plants. Fluorescent carbon dots have been synthesized using jamun juice (Syzygium cumini) as the carbon source subjected to surface modification with betaine (BT@JCD). This BT@ JCD exhibits strong blue fluorescence, which significantly decreases in the presence of Cr(VI) due to the inner filter effect in a range of 5− 450 nM with a detection limit of 0.033 μM. Due to its easy translocation in the vascular bundles, these fluorescence nanosensors can be applied to detect Cr(VI) in rice plants Oryza sativa) through fluorescence confocal imaging. The treatment of rice plants with BT@JCDs in the concentration range of 0.2 to 1g/mL not only triggered photophysical parameters such as carbohydrates, chlorophyll, and carotenoids but also enhanced the antioxidant enzyme activity promoting plant growth.

Cancer is one of the deadliest diseases that have a significant negative impact on the world’s enormous population. The chemotherapeutic medicines used in the treatment of cancer spread throughout the body causing general toxicity, poor patient compliance and even treatment cessation. This makes it difficult to deliver therapeutic agents to tumour cells with precision. Advancements in the field of medical science are being uplifted by the development of nanotechnology, which provides tremendous solutions to deal with such life-threatening diseases. Nanoparticles (NP) synthesised for medical purposes need to be biocompatible and low- or non-toxic. Therefore, the green generation of NPs is emerging as an alternative approach to physical and chemical methods. This study reviews the use of plants to synthesise these NPs. These are more stable than those synthesised from other biological sources. These NPs can be synthesised by using different metals such as gold (Au), silver (Ag), zinc (Zn), platinum (Pt), etc. Plant-derived green-manufactured Metallic Nanoparticles (MNPs) are extensively utilised in medicine as antibacterial, anti-inflammatory, anti-angiogenic and anti-cancer agents. Therefore, this review aims to study different green synthesised MNPs, their synthesis method, characterisation and their role in cancer therapy.
