Pesticide Residual Analysis By Surface-Enhanced Raman Spectroscopy(SERS)

Surface Enhanced Raman Scattering(SERS)was extended wide consideration as dominant spectroscopic apparatus have the capability of non-disruptive and ultra-trace findings to distinct compounds.It is a scattering technique which enhances the Raman spectra by using nanoparticles(NPs).Different researchers use different NPs for enhancement of Raman Spectra.The current research was done for fast findings of pesticides residue in fruits like mango,water melon and apple which depend upon surface enhanced Raman spectroscopy(SERS).Pesticides deposits was utilized to kills the bug and furthermore used to expand the yield of harvests.Pesticides residues in fruits was caused many diseases such as cancer and lungs problems.The filter paper was used as an absorbent wiper type SERS substrate.UV-visible and SEM instrument was utilized for description of silver nanoparticles(AgNPs).SERS was more significance than all others detection methods inclined toward research facility examination.The fundamental improvement of Raman signal essentially recognized to substrate of nanoparticles.Each peak in Raman spectra gives lot of specific information about pesticide residue.The spectral features were analyzed by statistical technique that involved Limit of Detection(LoD),Limit of Quantitation(LoQ),(PLSR)Partial Least Square Regression,T-test and standard deviation.So,in this research work the preparation of silver nanoparticles(AgNPs),analysis of structure of synthesized silver Nano particles(AgNPs),Fabrication of the SERS wiper and then to analyze the pesticides residue on the fruits.The results were shows that surface enhanced Raman scattering technique attaches with an elastic and permeable SERS substrate which was used as a consistent,fast and sensitive finding the pesticide on fruit skin.
