Welcome to Liposphere
Liposphere – where Biolubrication starts

Liposphere is a biomedical start-up spun out from the Weizmann Institute of Science (Israel) in 2019. Its unique IP-protected platform technology has been developed over the past two decades at the Department of Materials & Interfaces under Professor Jacob Klein. Based on the profound knowledge of Klein and his team, Liposphere is now developing an innovative platform of highly lubricous, water-based biocompatible nanomaterials for conditions in the human body where ultralow friction is of utmost importance.

Liposphere Answers Significant Unmet Medical Needs

There is an urgent global unmet medical need for the technology in mechanically stressed environments, including high-load conditions to which major joints such as the knee are exposed, where Liposphere will target Osteoarthritis, and low-load conditions such as the cornea-eye lid interface, targeting Dry Eye Syndrome.

Liposphere’s formulation can be used as a pure lubricant, but also has the potential to encapsulate active pharmaceutical ingredients in the future, for delivery of pharmaceuticals to targets that currently are difficult to reach.
In addition, Liposphere’s platform technology enables the coating of artificial medical surfaces such as contact lenses, catheters and protheses, giving the potential for smooth movement in a wide range of biomedical devices.

Liposphere’s Products

Liposphere’s first orthopedic biolubricant product, AqueousJoint, will target the Osteoarthritits market as an intraarticular injectable based on the rationale of market size, growth expectations and an unmet medical need. It is expected to be designated a medical device for regulatory approval. Furthermore, Liposphere has developed an ophthalmic formulation for the treatment of Dry Eye Syndrome. The formulation aims to reduce discomfort based on its unique lubricity and to provide patient-friendly dosing schemes due its long-lasting effect as a boundary lubricant.

The Companies Commercial Development

The Company recently secured seed funding from private investors and on June, 3rd 2019, the Israeli Innovation Authority announced supporting Liposphere within its Women’s Entrepreneur Track to develop AqueousJoint as an innovative treatment for Osteoarthritis, giving Liposphere a strong position for commercialization.

To explore Liposphere’s biolubricant platform technology further, the Company is currently seeking for partnerships with pharma/medtech companies in order to use the technology as a robust and efficient biomedical surface coating.
