Publication number: 20230270891Abstract: Liposomes have been used in technologies in biological, pharmaceutical, medical and nutritional applications because they can offer biocompatibility, biodegradability, reduced toxicity, and capacity for size and surface modifications. Traditionally, liposomes are prepared by multiple steps. However, multiple steps of preparation may cause a number of problems including low yield, high polydispersity, and poor morphology. Here, we synthesized liposomes containing magnetic iron oxide nanoparticle using one-pot, single step synthesis under ultra-sonication. We optimized the lipid compositions, sonication power, concentration of iron oxide nanoparticles, and antibody conjugation using Cu-free click chemistry. Furthermore, we incorporated doxorubicin inside magnetic liposomes for combined antibody targeting and magnetic guidance. Fluorescence imaging and quantification confirmed that antibody conjugated magnetic liposome showed high cell specific targeting that was enhanced by magnetic delivery.Type: ApplicationFiled: March 3, 2023Publication date: August 31, 2023Inventors: Konstantin Sokolov, Marie Zhang, Chang Soo Kim, Dmitry Nevozhay, Rebeca Aburto, Ashok Pehere, Lang Pang, John Hazle, Robert Clinton Bast

Publication number: 20180078659Abstract: Presented herein are methods of using encapsulated J-aggregates of indocyanine green (ICG) as a ratiometric sensor of biological activity. Upon interaction with a biological phenomenon of interest, the encapsulated J-aggregates can be released and dissolved upon rupture, inducing a detectable hypsochromic shift in the absorption spectra and corresponding increase in fluorescence. Various imaging techniques can be employed to visualize this sensor including photoacoustic imaging, two-photon imaging, fluorescence imaging, near infrared imaging, and a variety of other optical or optics-based techniques. Additionally, if the J-aggregates of ICG are also encapsulated with drugs or therapeutic molecules, the ratiometric sensing using ICG can be used to confirm drug release and delivery.Type: ApplicationFiled: February 7, 2016Publication date: March 22, 2018Inventors: Stanislav Emelianov, Konstantin Sokolov, Geoff Luke, Carolyn Bayer, Justin Harris, Albert Lee
