Polyrizon develops nasal barrier tech to block multiple respiratory viruses amid rising viral threats

Polyrizon Ltd. is advancing its Capture&Contain™ intranasal hydrogel technology that forms a protective barrier on the nasal mucosa to block various respiratory viruses, including influenza and coronaviruses. This non-specific mechanical barrier aims to provide immediate defense against emerging viral threats like Hantavirus, filling the gap before vaccines or treatments are available. The technology is still in pre-clinical development but shows promise as a broad-spectrum, fast-acting tool for pandemic preparedness and respiratory protection. Polyrizon seeks to position this platform as a complementary solution alongside future vaccines and antivirals to enhance public health resilience.
