Fulland Nano Files IPO Prospectus: Empowering Healthcare with Proprietary High-Purity Metallic Nanomaterials Platforms

“If the field of nanomaterials is a pyramid, then metal nanomaterials are the products at the tip of the pyramid,” said Cui Jianxun, founder and chairman of Furan Shi.

Compared with traditional nanomaterials such as carbon-based and polymer nanomaterials, metal nanomaterials are the most challenging to manufacture and offer the highest added value among all nanomaterials. Furthermore, metal nanomaterials have a wide range of applications, spanning hundreds of fields, including biomedicine, metal 3D printing, and precision electronics. The addition of small amounts of metal nanomaterials to industrial materials can significantly enhance or alter product performance; hence, metal nanomaterials are also referred to as “industrial vitamins.”

Producing metal nanomaterials with higher purity and uniformity has long been the pursuit of China’s nanotechnology enterprises. Fulangshi is a company dedicated to the research, development, and manufacturing of production equipment for metal nanomaterials. The company has independently developed such production equipment, filling a domestic gap. Metal nanomaterials produced using this equipment exhibit higher purity, with uniformity exceeding 99%, achieving true nanoscale dimensions.

Cui Jianxun, founder of Fullangshi, is a specially appointed expert in Beijing and a leading high-end talent in Zhongguancun. He has obtained more than 20 national patents in the field of metal nanomaterials. At the end of 2012, Cui Jianxun, who had worked at Alcatel-Lucent for many years, responded to the call for overseas students to return to China for entrepreneurship and came back to China. In 2013, he founded Fullangshi, focusing on the research and development of production equipment for metal nanomaterials and the industrial mass production of metal nanomaterials, covering both equipment manufacturing and metal nanomaterial manufacturing.

Cui Jianxun has over a decade of experience in the field of nanomaterials and possesses a profound understanding of the industry’s pain points: “There are nearly 1,000 nanomaterial companies in China, ranging from large to small enterprises, representing a substantial number. However, most of these companies directly purchase advanced foreign equipment for production, focusing on process treatment and material modification after producing new materials. While process treatment and material modification are undoubtedly important, the fact that everyone is crowding into this segment, with no company dedicating efforts to the research and development of nanomaterial production equipment, poses a significant risk.”

The core barrier for nanomaterials lies in production equipment, which is precisely the most challenging aspect of the nanomaterials field. Independently developing production equipment requires substantial investment of time and resources, precluding rapid profitability in the short term. Frolans has chosen the most arduous path.

Over the past few years, FuranSys has overcome numerous challenges, completed the research and development of equipment for metal nanomaterials, mastered key technologies in metal nanomaterial manufacturing, and is currently in the phase of significantly scaling up mass production. Meanwhile, the company has entered a harvest period and begun to achieve rapid growth. In 2015, the company won first place in the inaugural Overseas Returnees Innovation and Entrepreneurship Competition; in 2016, it was successfully listed on the New Fourth Board; in 2018, it claimed the overall championship at the “Beijing-Tianjin-Hebei–Guangdong-Hong Kong-Macao International Youth Innovation Competition”; and in 2019, it was awarded the title of “Zhongguancun Annual Entrepreneurial Star.” Additionally, the company has completed its Series A financing round, garnering favor from multiple investment institutions, including Tsinghua University and China Ocean Investment.

There are three major processes for manufacturing metal nanomaterials: physical milling, chemical reduction, and electrical explosion. Metal nanomaterials produced by physical milling contain numerous impurities. Although the chemical reduction method offers high yield, it results in significant chemical residues. The electrical explosion method features high production capacity, minimal environmental pollution, and higher material precision, making it currently the most advanced process for preparing metal nanomaterials.

The metal nanomaterial production equipment developed by Fulangshi employs the internationally leading electrical explosion method, which utilizes high-voltage currents of tens of millions of volts (equivalent to artificial lightning) to impact the metal surface, causing the metal to explode and form metal nanoparticles with controllable particle sizes.

Different metal materials have distinct physicochemical properties. In response to these varying indicators, Fulan Shi has implemented differentiated parameter controls for its equipment. Cui Jianxun stated, “Our equipment is user-friendly, with parameter control integrated into the software system. It does not rely on highly experienced operators and is suitable for research institutions, university laboratories, and industrial production.”

It is understood that Fulan Shi’s metal nanomaterial production equipment offers higher productivity, yielding metal nanomaterials with greater precision and purity at lower costs, while ensuring zero environmental pollution during the manufacturing process. The system can produce thousands of different specifications of metal nanomaterials, including those that are highly challenging to fabricate, such as tungsten nanoparticles, aluminum nanoparticles, and nickel-titanium alloys.

Currently, metal nanomaterials produced by Furuangshi have been applied in various fields, including biomedicine, electronics, metal 3D printing, solid fuels, nano-coatings, and nano-lubricants. Among these, metal nanomaterials hold significant application potential in the biomedical field. For instance, gold nanomaterials and silver nanoparticles can serve as drug carriers; nano-silver exhibits antibacterial properties and can be used for medical disinfection; and nano-titanium dioxide can be utilized in tumor therapy to selectively kill tumor cells while reducing toxic side effects.

Cui Jianxun predicts that metal nanomaterials will play an increasingly important role in the pharmaceutical and medical fields. “Currently, some cutting-edge drugs and diagnostic technologies cannot be widely adopted due to their prohibitively high costs. Metal nanomaterials offer a solution to this challenge. Moving forward, the company will focus on the application of metal nanomaterials in the biomedical sector, leveraging its expertise in this area to empower the industry.”

Previously, Fulland had been focused on supplying raw materials to B2B clients. The sudden outbreak of the COVID-19 pandemic pointed the company toward a new business direction.

Cui Jianxun stated, “The impact of the COVID-19 pandemic is no less than that of SARS; it constitutes a crisis for every enterprise. ReLanShi’s R&D, production, and operations have all been affected.” However, Cui Jianxun believes that every crisis presents an opportunity. “After the outbreak, management began to consider how to leverage our existing technological expertise and accumulated capabilities to meet market demands during the pandemic and demonstrate corporate value.”

Lanxess has observed that the pandemic has triggered a surge in consumer demand for disinfection and sterilization products, leading to supply shortages. Nano-silver can release silver ions, which destroy bacterial proteins upon contact, thereby killing bacteria and achieving sterilization. Notably, the novel coronavirus has been detected to contain thiol proteins, suggesting the potential for silver ions to inactivate the virus by targeting these sulfur-containing proteins.

Leveraging the excellent disinfecting and antibacterial properties of nano-silver, Fulanshi has developed complexed silver disinfectant/antibacterial solution and antibacterial film to support epidemic prevention and control.

The antibacterial solution developed by Fulangshi has no side effects on the human body. A single spray provides protection for up to one week, offering high-efficiency, broad-spectrum disinfection capable of eliminating over 650 types of lethal pathogens. Testing by a national-level third-party inspection agency has confirmed that the product demonstrates significant efficacy in eradicating Staphylococcus aureus and Escherichia coli.

This bacteriostatic solution is odorless, non-irritating, and non-flammable. It can serve as an alternative to conventional disinfectants and alcohol, making it suitable for large-area spraying via drones. It is ideal for disinfection in high-density settings such as factories, hospitals, communities, schools, shopping malls, and transportation hubs, as well as for household disinfection and protection.

Building upon traditional protective films, Fulangshi incorporates company-prepared nano-silver, endowing the product with specialized antioxidant and antimicrobial properties. It offers broad-spectrum, long-lasting antibacterial, bacteriostatic, deodorizing, and anti-mold functions, achieving an inhibition rate of over 99% against microorganisms such as Escherichia coli and Staphylococcus aureus, with efficacy unaffected by light or water.

This product is suitable for hospital isolation and protection, and can be used as material for isolation tents, protective suits, and protective gloves. According to Cui Jianxun, this antibacterial film has already been applied in Wuhan’s makeshift hospitals, China CITIC Bank, and other institutions.

Cui Jianxun stated that the current epidemic has brought new opportunities and a turning point for Fulangshi. “Due to the impact of the epidemic, public awareness of disinfection and sterilization has significantly improved, leading to expanded market demand for disinfection and sterilization products. Moving forward, the complexed silver disinfectant and antibacterial solution and the antibacterial film will be operated as independent business units.”

Post-pandemic, Runan Shi will shift from a B2B-only model to one that equally emphasizes both B2B and B2C operations. In the future, in addition to providing metal nanomaterials and equipment to business clients, the company will focus on developing more consumer-oriented products. “We aim to serve a broader population and create a better living environment through our core technologies.”
