“…Se et al 182 used chemometric analysis for the determination of Ca, Mg and Na content in honey. The challenges for application of LIBS in agricultural studies were discussed in a recent review by Peng et al 183 Eum et al 184 discussed the combined use of LIBS and near-infrared spectroscopy for the identication of the geographical origin of vegetable samples. Atta et al used LIBS for the quantication of micro-nutrients (zinc, iron) in wheat, 185 noticing that LIBS analysis can be useful for growers in selecting the wheat genotypes richer in these micronutrients.…”

“…Water molecules form a complex and flexible hydrogen bond network [8], which is highly sensitive to external factors such as pH, temperature, and solute concentration [9]. Near-infrared (NIR) spectroscopy has emerged as a powerful tool to investigate water structures [10][11][12] and has been well studied in experimental [13][14][15] and theoretical calculations [16][17][18]. Six absorption peaks were obtained from derivative spectra, corresponding to the rotational vibrational peak of water molecules (S r ) and the characteristic peaks of water molecules with zero to four hydrogen bonds (S 0 -S 4 ) [19].…”

Accurate determination of extra-cellular pH (pHe) and intra-cellular pH (pHi) is important to cancer diagnosis and treatment because tumor cells exhibit a lower pHe and a slightly higher pHi than normal cells. In this work, the characteristic absorption of water in the near-infrared (NIR) region was utilized for the determination of pHe and pHi. Dulbecco’s modified eagle medium (DMEM) and bis (2-ethylhexyl) succinate sodium sulfonate reverse micelles (RM) were employed to simulate the extra- and intra-cellular fluids, respectively. Continuous wavelet transform (CWT) was used to enhance the resolution of the spectra. Quantitative models for pHe and pHi were established using partial least squares (PLS) regression, producing relative errors of validation samples in a range of −0.74–2.07% and −1.40–0.83%, respectively. Variable selection was performed, and the correspondence between the selected wavenumbers and water structures was obtained. Therefore, water with different hydrogen bonds may serve as a good probe to sense pH within biological systems.

“…Considering the advantages of LIBS and NIRS in analyzing crop elements and organic components, data fusion is expected to achieve better results in identifying rice varieties. At present, the data fusion of LIBS and NIRS has been successfully reported in the qualitative analysis of the navel orange Huanglongbing 24 and the identification of domestic and imported samples 25 . However, it has not been applied to the authenticity identification of rice varieties.…”

This study proposes a method to rapidly determine the authenticity of hybrid rice seeds using the fusion of laser-induced breakdown spectroscopy (LIBS) and near-infrared spectroscopy (NIRS). The male parent, F1 generation, and female parent of two hybrid rice vaieties ("Zhongheyou 1" and "Liangyou 688") were identified by the proposed method. The LIBS and NIR spectra of rice seeds with different physical state (single rice kernels [SRK] and single brown-rice kernels [SBRK]) were measured, and the primary fusion and intermediate fusion were used for the construction of the LIBS and NIRS data fusion models. The comparation results under different conditions show that the intermediate SRK and SBRK fusion models achieve the best test accuracy (96.88% and 98.52% for "Zhongheyou 1", and 98.96% and 95.26% for "Liangyou 688", respectively). The results indicate that the proposed method is effective for rapid and accurate identification of parents and progenies of hybrid rice.
