1. Instant Generation of NO

Novlead owns a series of core technologies for instant nitric oxide generation, facilitating the accurate and quick generation of high-purity nitric oxide gas with adjustable concentration and no harmful impurities in real time. It is suitable for a wide range of clinical scenarios for patients with pulmonary hypertension, pulmonary fibrosis and other indications, as a safe and reliable portable nitric oxide gas treatment source.

a. Instant Generation of NO---Electrochemical Catalytic Reduction：
NO generation technology uses transition metal ions having multiple valence states as the catalytic core. The metal ion in the high-valence state is changed to the  low-valence state by a precisely controlled current, reducing the nitrite ion  to NO. At the same time, the metal ions return to the high valence state and  participate in the new round of reaction process.

● NO concentration can be precisely regulated by electric current, immediate, safe and controllable

● Pure NO gas with no by-products other than NO

● No high temperature or pressure needed, the gas is transferred always in room temperature

● Combined with highly efficient nitrogen generation technology, the NO generated uses nitrogen as the carrier  gas, minimizing therisk of exposure to harmful byproducts such as NO2

b. Instant Generation of NO---High Temperature Plasma Air Conversion
By using high voltage, nitrogen and oxygen in the air are converted into high temperature plasma, where nitrogen and oxygen atoms recombine to produce NO,  and also inevitably produce a small amount of NO2 and other impurities and   trace metal particles. The specially designed filter contains a multiple filtration system to absorb impurities while effectively filtering particles to ensure the safety and purity of the user's gas.

● The reactants are taken from air directly, no storage, no extra charge for the  feedstock

● The machine is small and portable, suitable for transit and other scenarios

● The filter is supported by a unique algorithm to ensure that the gas is  effectively purified while the service life is extended as much as possible,  and can be used for long-term stable treatment without frequent replacement

2. Controlled Release of NO

NO sustained release technologies are based on a variety of NO donors (compounds that release NO  under specific conditions). Suitable materials can be provided through  in-depth research on various donor molecule design, gas loading technology,  sustained release condition control and process production, meeting diverse  medical and consumer needs according to different application demand scenarios.

a. Design and Development of NO  Controlled-Release Molecule

Based on the different requirements of NO action time and concentration required for  vasodilatation, antibacterial and antiviral, engineered tissue regeneration,  anti-aging, pain management, environmental disinfection, etc., according to  the release mechanism and action path of endogenous and exogenous NO gas  molecules, reasonable corresponding NO donor structure molecules are designed to  ensure accurate and controllable release and use.

b. Gas Loading Technology

Combined with the molecular characteristics of different donor structures, inorganic nanoparticles,  natural organic polymers, and organic porous membrane materials are used as  gas carriers to achieve a high degree of integration of NO and the stability of donor structures for stable storage.

c. Control of Sustained-Release  Conditions

According to the requirements of different application scenarios, the donor molecules and carriers are screened, and the  sustained release conditions are controlled by adjusting the catalyst, light,  sound wave, temperature, ph, etc., to achieve stable and on-demand release of NO gas in specific scenarios.

d. Consistent Process Requirements

Process verification of Class-10000 purification workshop, and continuous optimization of the whole  production process of NO donor materials and products to ensure high purity and high quality of products, with minimal differences between product batches.

e. Various Product Dosage Forms

Based on the sustained release of NO technology, we develop diversified product forms, including liquid, paste, emulsion, gel, coating, granule, etc.,  involving Class I and II medical devices, disinfection products, cosmetics,  etc., to meet the needs of different customers and different fields.
