• equal sides are obtained (see Figure 6C1). This result is consistent with Hyllested et al. [38] who also obtained AgNPs with triangular morphology using pineapple extract. The synthesis temperature plays an important role in the formation, growth, and size distribution of nanoparticles, as mentioned by

• extinction appears in the red and near infrared region. For pineapple extract, the formation of silver nanoparticles is a faster process. The first sign of a plasmonic band can be seen already after 4 minutes and the process stops after 30 minutes. The peak of the plasmon spectrum appears at 450 nm and shows

• a small red shift over time. This shift indicates that for pineapple extract, not only the number of particles increases over time, but also the size and morphology of the particles change. An interesting property of green silver nanoparticles is their capability as enhancing plasmonic structures in

• gave rise to round and almost spherical silver particles, reduction by pineapple extract results in particles with sharp corners. However, not only the kind of fruit determines size, shape and speed of growing of silver nanoparticles, also other experimental parameters during the green preparation
