Identify a recent research article (not review) that uses either confocal microscopy or super-resolution microscopy as one of the study's techniques. Explain briefly (1 paragraph) how the microscopy technique specifically contributed to the article's findings.
This study examined the chemotherapeutic drug doxorubicin (DOX) with the novel sixth-generation cationic poly-l-lysine dendrimer (DM) and determined enhanced therapeutic efficacy of DOX when complexed to DM in tumour-bearing mice. Confocal microscopy allowed evaluation of the depth of distribution of both drugs (DOX and DOX-DM) into the Multicellular Tumour Spheroids (MTS)bu the following method. For each image, intensity from background fluorescence was obtained from untreated MTS and subtracted from total intensity. The total fluoresence intensity was then calculated in each region of interest and plotted as a function of the distance from the spheroid rim. 
1. Select 4 reference papers related to your selected topic sub-section. Read these papers and write a brief description of their findings and relevance to the selected topic sub-section. The reference along with your description should then be pasted on both your group discussion page and your own personal page. 2. Select an image related to your selected topic sub-section (this can be from one of the 4 above or from elsewhere). The image should be uploaded (with all the required information: description, reference, copyright and student template) and pasted onto the project page sub-section and onto your own personal page.
