This material releases a drug called MZ1 in a controlled manner by means of small particles known as <strong>liposomes<\/strong>. The novelty of this model is that it takes into account key factors such as the absorption of the drug by the cells, lymphatic drainage and even the influence of gravity on its distribution.  <\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"817\" src=\"https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-1024x817.jpg\" alt=\"\" class=\"wp-image-5261\" srcset=\"https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-1024x817.jpg 1024w, https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-300x239.jpg 300w, https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-768x613.jpg 768w, https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-1536x1225.jpg 1536w, https:\/\/ibsal.es\/wp-content\/uploads\/2025\/02\/1-s2.0-S0928098724002793-gr1_lrg-2048x1633.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>To test its effectiveness, the research team used MRI scans of six patients with different types of tumors.
