Surfactant assisted exfoliation of near infrared fluorescent silicate nanosheets

“…Improvements in the preparation of EB-NS could become very important for applications that require environmentally save materials in larger quantities such as precision agriculture or biomedical imaging. 11,[58][59][60] In summary, our efficient large-scale exfoliation process makes applications such as the use of EB-NS as macroscopic NIR barcodes possible. It paves the way for further fundamental studies of the photophysical properties of EB-NS as well as applications in NIR photonics.…”

A nIR fluorescent single walled carbon nanotube sensor for broad-spectrum diagnostics

“…Nissler et al found that various structures of polyphenols could be detected if the SWCNT surface was non-covalently modified using ssDNA and PEG-lipid macromolecules with different surface chemistries and different nucleotide compositions. 100 The rationale behind this approach is that compounds such as tannins have multiple hydroxy groups and can influence SWCNT sensors to form strong interaction with polyphenols. To inject the SWCNT sensors into plants, these sensors were embedded in culture medium agar and soybean seedlings were grown on it.…”

Imaging tools for plant nanobiotechnology

“…Similarly, ss (GT) 15 oligonucleotides-encapsulated SWCNTs were designed for in vivo H 2 O 2 detection in plant leaf (Lew et al, 2020b;Wu et al, 2020). This technique has also been used in plants for in vivo polyphenol (Nissler et al, 2022), nitroaromatic compounds (Wong et al, 2017), and Arsenite (Lew et al, 2021) detection in plants. Other nanomaterials, such as luminescent lanthanide metal-organic frameworks (Ln-MOFs), were developed for the detection of metal ions (Ag + , Cd 2+ , Fe 3+ , Cu 2+ ) in plants (Liang et al, 2020).…”
