Nanoparticles (NPs) show promising applications in biomedicine, catalysis, and energy harvesting. This applicability relies on controlling the material’s features at the nanometer scale. Surfactants, a unique class of surface-active molecules, have a re

The sharpness of the bands indicated that the bonds were mostly uniform in nature. According to the SEM analysis, as shown in Figure 1(d) to (e), the solid C60 consisted of particulate aggregated C60 ~200 nm with a regular spherical form. Smaller-sized particle grains were also observed,...
To understand the components of different meat proteins, SDS-PAGE was used to analyse the protein patterns (Jia et al., 2019). Under reducing conditions, proteins were disrupted, unfolded, and stretched, and intramolecular disulphide bonds were destroyed. The separation of different proteins was ...
Moreover, Another possible reason was that HIUS treatment caused the fracture of hydrogen bonds and exposure of the hydrophobic regions within the protein molecules [26]. The changes in the secondary structure of soy protein [4] and bovine serum albumin [27] treated by HIUS were consistent ...
Generally, it was observed around the region of 250–400 nm; however, the exact position, shape and numbers varied according to particles surface modification which include agglomeration state, particle morphology, size, surrounding medium chemistry and synthesis method30,31. Obviously, the ...

(Fig.7a). The advantages of using DA was that DA can not only react with GO to form covalent bonds but also self-polymerize into long-chain polymers of poly(dopamine) (PDA) through its abundant functional groups (Fig.7b). The strong interfacial crosslinking resulted in the curving of the...
