Graphene is a very research-intensive and multi-purpose substance, which may revolutionize all aspects of our lives: for example, it is used to produce waterproof membranes to solve the global water shortage problem; it replaces the silicon in current electronic products with smaller The volume provides stronger performance; the development of next-generation energy solutions, such as solar cells or mobile phone batteries that can be fully charged in minutes. In addition, graphene can also be used in biomedical fields, such as drug delivery, cancer treatment, and biosensing, and researchers are currently conducting related research. Graphene has many unique properties, such as larger surface area, biocompatibility and chemical stability, which makes graphene has great research potential and is given high hopes.

The biomedical industry is known as the "sunrise industry that never declines." With the development of the world economy, changes in the living environment, changes in people‘s health concepts, and the acceleration of population aging, the biomedical industry, which is closely related to the quality of human life, has maintained a continuous growth trend in recent years. The pharmaceutical industry has developed rapidly and has become one of the fastest-growing high-tech pillar industries in the world with the most significant economic benefits. In developed countries such as Europe, America and Japan, the profit rate of the pharmaceutical industry ranks first in various industries, reaching 17.2%, which is significantly higher than the second-ranked telecommunications industry (8.1%) and the third-ranked computer industry (7.3%).

Global biomedical industry distribution map
In recent years, graphene has entered the high-tech industry biomedicine industry with its excellent biocompatibility and aqueous solution stability, which has injected new impetus into the development of the industry and has reached a certain level in technology. In a society with rapid economic development, national health is always the first. Graphene solves more medical problems with its excellent performance and will play an irreplaceable role in the biomedical industry.

For example, it can be used as a cell growth scaffold to synthesize a composite material highly compatible with cells such as polysaccharides, and be implanted into the human body. The functionalized nanographene can also be used as an effective carrier to transport anticancer drugs for chemotherapy to the cell. In, improve the treatment effect and efficiency. Graphene-based biological devices or biosensors can be used for bacterial analysis, DNA and protein detection. For example, the graphene nanopore device developed by the University of Pennsylvania can quickly complete DNA sequencing. Graphene quantum dots are used in biological imaging. Compared with phosphors, they have the characteristics of more stable fluorescence, no photobleaching and less light decay.

The application of graphene in nano-drug delivery systems, biological detection, tumor treatment, and cell imaging has filled some gaps in biomedical technology and played an important role in promoting the development of the biomedical industry. Although the application research of graphene in the field of biomedicine is in its infancy, it is one of the most promising application fields for industrialization.

Artificial implant equipment
Artificial implanted devices are the main theme of the current medical market, and graphene may play an extremely important role in these devices in the future. Graphene‘s biocompatibility and mechanical strength can be used to make various composite biomaterials; its conductivity can be used for organs that require this property, such as nerve tissue and spinal cord elements. For example, researchers at Michigan Technological University have made progress in introducing graphene into 3D printed nerve tissue. The team developed a polymer material to cultivate tissues, using graphene as a conductor.

biological sensor
Biosensing is a rapidly developing new technology with the potential to be applied to many medical applications. Graphene has unique advantages in detecting food toxins, environmental pollution, specific germs and bacteria. For example, attaching graphene oxide to the protein-like structure of a specific toxin can generate an enhanced signal for highly sensitive detection of the toxin, and its detection capacity is equivalent to 10 times that of ordinary sensors. In addition, in the use of sensors to predict heart attacks, graphene oxide can also detect specific particles in the blood, and these particles are released before the heart attack. Currently, similar sensors based on graphene are under development, mainly used to detect various diseases, toxins and biomarkers.

Drug delivery and cancer treatment
Graphene also has great potential to detect and treat cancer. In terms of detection, Chinese scientists have developed single-cell sensors based on graphene field-effect transistors, which can even detect single cancer cells. Researchers at the University of Manchester in the UK have discovered that graphene oxide can be used as an anti-cancer agent to fight specific cancer cells. With current therapies, it may shrink tumors, curb the rate of cancer development, and recurrence after treatment.

Graphene has also been widely studied for the delivery of cancer drugs, mainly due to its large surface area allowing large amounts of drugs to be delivered to specific areas in the body. In addition to being used for cancer detection and drug delivery, graphene itself has also been studied as an anti-cancer agent. For example, using its thermal conductivity properties to convert non-ionized radio waves into heat energy to kill proteins and DNA in cancer cells.

DNA sequencing
The importance of DNA sequencing is becoming more and more prominent. It can not only have a deeper understanding of human composition, but also further understand genetic diseases, cancer types and the human immune system. Graphene-based DNA sequencing usually requires the creation of a graphene film, immersing it in a conductive fluid, and applying electricity at one end to allow DNA molecules to pass through the small holes in the graphene, allowing scientists to read the DNA sequence. This technology is called "nanopore DNA sequencing" and is characterized by fast reading and low sequencing cost.

At present, the application of graphene in the biomedical industry is still in its initial stage. It is believed that the mature application of graphene will promote the rapid development of the biomedical industry at an unprecedented speed in the near future. In recent years, the support of national policies and the needs of national health have promoted the rapid and stable development of the biomedical industry. It is conservatively estimated that China‘s graphene will account for 1/3 or more of the market size of the biomedical industry, which will correspondingly promote the continuous increase of the market share of the biomedical industry, and the entire pharmaceutical industry will undergo a revolutionary transformation.
