Background: Synchrotron Radiation X-ray fluorescence analysis is an advanced method of quantitative elemental analysis.It is a scientific platform for life science
material science
and environmental science.Purpose: In this present study
the drug loading behavior of dendrimers nano-vectors was investigated by using the method of Synchrotron Radiation X-ray fluorescence analysis.Methods: The copper(II) ions were loaded into acetyl-modified generation 5(G5) PAMAM dendrimers.We monitored and imaged the distribution of copper in A549 cell by Shanghai Synchrotron Radiation Facility(SSRF) to observe the cellular uptake of copper-dendrimers conjugates.Results: The results of hard X-ray fluorescence mapping showed a stronger fluorescence of Cu in the cells treated with G5-Ac-Cu than that of control.Conclusions: This investigation provided a method of using synchrotron radiation X-ray fluorescence analysis to study the drug loading behavior of dendrimers.
