meet such criterion has been widely reported in the literature [8-9]. Such surfaces
might produce surfaces with minimal background interference.
28.4 Conclusions and Recommendations
1. SSHG signal modulations were detected by the modified SSHG experimental
system. This indicated the ability of the SSHG experimental setup to distinguish
between different deposited layers.
2. Passing & Bablok Regression analysis between the ELISA optical densities for
segments (showing linear correlation with dilution steps) and corresponding
∆SSHG interact , indicated that the modulations in SSHG signals were not linked to
the bio interaction between Ag and their PAbs.
3. Possible reasons for the lack of agreement between SSHG spectroscopy ELISA,
could be due to the lack of homogeneity within the matrix of microwells, lack of
precision of sampling by SSHG or random orientation of biomolecules, in addition to experimental errors.
4. To further investigate SSHG capability, the use of oriented immobilisation would
be highly recommended.
