Here, we report an environmentally friendly fabrication strategy of bright yellow fluorescent carbon dots (y-CDs) and construct a rapid and accurate multifunctional sensing platform for the effective detection of temperature and Cu2+.
Fluorescent carbon dots (CDs) bioinspired from sulfonated glycosaminoglycan were elaborately designed and fabricated via a facile hydrothermal synthesis, effectively achieving the cellular imaging and regulating behaviors of mesenchymal stem cells.
