AuNP@Self-assembled 4H-Chromene-Enhanced colorimetric detection of ganciclovir using smartphone Technology: Portable solutions for healthcare
Any substance, radiation, or radionuclide in our environment that promotes carcinogenesis is a cancerogen. In the current work, we modified the 4H-chromene derivative by covering its surface with a shell of gold nanoparticles. Interestingly, ganciclovir (GCV) formed a bridge between the Nap-group of 4H-chromene and gold nanoparticles to display surface charge reduction properties in AuNP@Self-assembled 4H-Chromene. The surface charge of AuNPs is reduced as a result of the electron transfer mechanism brought on by the creation of the Nap-GCV-AuNP link, which leads to agglomeration. This led to the development of a dual-mode colorimetric sensor for GCV that incorporates solution form and portable sensor strip. The probe showed a linear range of 0–74 nM under ideal circumstances, with a detection limit of 4 nM in solution and 3 nM on paper strip detection. An evaluation of the practical utility in human serum using a portable visual read-out produced satisfactory findings, with a recovery percentage of 102.1 % and a standard deviation of ± 4 %. Surprisingly, this is the first work on the colorimetric detection of Ganciclovir that we are aware of.
期刊介绍:
The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
