Simultaneous determination of rifampicin, isoniazid, pyrazinamide and ethambutol in 4-FDC tablet by Raman spectroscopy associated to chemometric approach

Raman enhancement effect of different silver nanoparticles on salbutamol

“…The pre-processing method of Automatic Whitacre Fitting Algorithm (AWF) was used to remove the fluorescence background of Raman spectra after acquisition. Correlation coefficient ( R c ), root mean square error of correction ( RMSE c ), prediction coefficient ( R p ) and root mean square error of prediction ( RMSE p ) were used to evaluate the performance of the models ( Chellini et al., 2017 ). Higher R p , R c values and lower RMSE c , RMSE p values demonstrate better model performance ( Guo et al., 2021 ).…”

An ultrasensitive electrochemical sensing platform based on silver nanoparticle-anchored 3D reduced graphene oxide for rifampicin detection

“…5 Thus, it is significant to assess the level of RIF simply and accurately in drugs, food and human blood samples. Multiple analytical methods have been used to analyze RIF, such as UV–visible spectrophotometry, 6 chemiluminescence, 7 Raman spectroscopy, 8 high-performance liquid chromatography (HPLC) 9 and mass spectroscopy (MS). 10 Nevertheless, these methods often require difficult sample preparation, have complex pretreatment steps, are time consuming and bear high costs.…”

Bimetallic cobalt–iron diselenide nanorod modified glassy carbon electrode: an electrochemical sensing platform for the selective detection of isoniazid

“…A variety of analytical approaches such as high-performance liquid chromatography, Raman spectroscopy, chemiluminescence, colorimetry, capillary electrophoresis, uorimetry, chemometry, titrimetry, polarography, and spectrophotometry are used for INZ analysis. [5][6][7][8][9] All these techniques have their own advantages but every technique has some limitations. Therefore, efforts are underway to search for effective tools on case to case basis.…”
