Molecular imaging of tumour-associated pathological biomarkers with smart nanoprobe: From “Seeing” to “Measuring”

Peisen Zhang, Wenyue Li, Chuang Liu, Feng Qin, Yijie Lu, Meng Qin, Yi Hou

The “smart” nanoprobe-based quantitative molecular imaging can mathematically visualize the tumour-associated pathological biomarkers, such as proteins, nucleic acids, or metabolites, enabling it possible to quantitative monitor the spatiotemporal evolution of the pathological characteristics inside the tumors accurately, and contributing to improving prognosis and therapeutic intervention by enabling precise and individualized theranostic strategies.

Global warming has posed significant pressure on agricultural productivity. The resulting abiotic stresses from high temperatures and drought have become serious threats to plants and subsequent global food security. Applying nanomaterials in agriculture can balance the plant’s oxidant level and can also regulate phytohormone levels and thus maintain normal plant growth under heat and drought stresses. Nanomaterials can activate and regulate specific stress-related genes, which in turn increase the activity of heat shock protein and aquaporin to enable plants’ resistance against abiotic stresses. This review aims to provide a current understanding of nanotechnology-enhanced plant tolerance to heat and drought stress. Molecular mechanisms are explored to see how nanomaterials can alleviate abiotic stresses on plants. In comparison with organic molecules, nanomaterials offer the advantages of targeted transportation and slow release. These advantages help the nanomaterials in mitigating drought and heat stress in plants.
