PEDOT nanoparticles with a suitable nanosize of 17.2 nm, broad adsorption from 700 to 1250 nm, and photothermal conversion efficiency (η) of 71.1%, were synthesized using an environmentally friendly hydrothermal method. Due to the electrostatic attraction between indocyanine green (ICG) and PEDOT, the stability of ICG in aqueous solution was effectively(More)
The side effects of chemotherapy bring significant physical and psychological suffering to patients. To solve this urgent medical problem, Yb3+ and Er3+ co-doped NaLuF4 upconversion nanoparticles (UCNPs) were constructed for upconversion luminescence (UCL)-labeled diagnosis under 980 nm laser irradiation. The UCNPs were then modified layer by layer with(More)
Nisin fermentation by Lactococcus lactis requires a low pH to maintain a relatively higher nisin activity. However, the acidic environment will result in cell arrest, and eventually decrease the relative nisin production. Hence, constructing an acid-resistant L. lactis is crucial for nisin harvest in acidic nisin fermentation. In this paper, the first(More)
Lactococcus lactis is a gram-positive bacterium used extensively in the dairy industry and food fermentation, and its biological characteristics are usually improved through genetic manipulation. However, poor transformation efficiency was the main restriction factor for the construction of engineered strains. In this study, the transformation efficiency of(More)
