American Marconi Wireless News - Altamira Therapeutics Announces Successful Nanoparticle-Based Delivery of DNA Molecules

HAMILTON, BERMUDA / ACCESS Newswire / November 3, 2025 / Altamira Therapeutics Ltd. ("Altamira" or the "Company") (OTCQB:CYTOF), a company dedicated to developing and commercializing nucleic acid delivery technology for targets beyond the liver, today announced that its nanoparticle-based delivery platform was successfully tested to deliver DNA molecules. In vitro experiments demonstrated efficient transfection of cells and reliable expression of the encoded proteins. Altamira will start offering its xPhore^™ platform for DNA delivery under the specific GenePhore^™ label, complementing its offerings for short RNA (OligoPhore^™), linear mRNA (SemaPhore^™) and circular RNA (CycloPhore^™).

"GenePhore is yet another impressive example for the strong capabilities and versatility of Altamira's peptide-based nanoparticle delivery platform," commented Covadonga Pañeda, Ph.D., Altamira Therapeutics' Chief Operating Officer. "Delivery of DNA molecules such as plasmids has remained a major challenge for drug and vaccine developers. Our xPhore technology provides for effective cellular uptake and strong endosomal release into the cell even for such large payloads. We are excited to collaborate with partners to apply this technology across fields such as DNA vaccines, gene editing, or protein replacement therapies."

GenePhore is addressing a large and growing market opportunity. Based on independent research, the global gene delivery technologies market size was estimated at $5.35 billion in 2024 and is expected to exceed $22.8 billion by 2034.[1]
