• significant color change (yellow to brownish-yellow) in the presence of Cd2+ and Pb2+ (Figure 5c). The color and absorption spectra change can be attributed to the nanoparticles’ aggregation [31]. A slight increase in the intensity of ʟ-car-AgNPs after the addition of Cr3+ ions was also observed, possibly due

• them, a linear polymer was constructed through consecutive inclusion of adamantane in β-CyD units. Upon further addition of poly(ethylene glycol) bearing adamantane at the terminus nanoparticles were formed (Figure 7B). In these nanoparticles, aggregation of porphyrins is suppressed because of steric

Similarly, CNPs induce mild aggregation only, regardless of the presence of several proteins involved in the coagulation cascade in the hard corona of the NPs. On the other hand, with large carbon nanoparticles, aggregation was observed for a prolonged

On the other hand, the wet reduction is the most common synthetic technique for the fabrication of metal nanoparticles, using sodium borohydride as a reducing agent and thiols as a capping agent to prevent nanoparticles aggregation [44][45][46].
