Bacterial cellulose (BC)-Nanoskin® has become established as a new biomaterial and can be used in several medicine areas, especially for medical devices mainly in dental and orthopedics applications. In addition, biomaterials have rise because of the increased interest in tissue engineering and regeneratine medicine materials for wound care and skin cancer treatment. The BC process production can be changed by different fermentation process. It has particular properties that make it an ideal candidate as a medical material: high mechanical properties, biocompatibility to the host tissue, and production in various shapes and sizes. This review describes a behavior investigation of this biomaterial in human medicine with bacterial cellulose, skin cancer, covid-19 and 3-D print for medical area.

Cancer cells can be proliferating in a few months and years. It depends on cancer stage. Chemotherapy, immunotherapy and anti-metabolic drugs have been used in order to kill cancer cells and prevent immune system weakly and metastasis. However, such drugs can damage healthy cells too. Natural ways to cancer treatments may help whole body to cancer cells. In this work, it was taking off cancer nodule to skin cancer by surgery and we treat the nodule as wound, using Nanoskin® advance cell therapy (ACT), natural extra cellular matrix which releases nutrients to the skin cancer. Our result shows that the cancer nodule disappears in few weeks in skin, because of natural membrane treatment. In addition, we obtained complete wound healing due anticancer nutrients (beta-glucan) delivery to skin.

3D printing is the future. It will change the way in which we produce new materials—maybe much less in factories and much easier in shops. However, biobased materials have been difficult to 3D print. Most 3D printers use heat to melt the plastic or metal to be printed, and biobased materials are degraded. But cellulose nanofibrils have a solution to this problem: the printing paste is wet and dries out to a solid material. In this work, it was showed recent wound healing in Vinous Ulcer with kidney and other health complications using bacterial cellulose 3D print membranes.

Natural Nanoskin Advance cell therapy (ACT) and Nanoskin ACT Soft have been established to be remarkably versatile biomaterials and can be used in a wide variety of applied scientific endeavors, especially for medical devices. In fact, the structure of Nanoskin materials can be adapted over length scales ranging from nano to macro by controlling the bio-fabrication process. The present paper describes Natural Nanoskin Advanced cell therapy (ACT) and Nanoskin ACT Soft production for wound care applications. ACT is produced from the bio-nanotechnology process. ACT is a highly hydrated pellicle with shaped fibers less than 2 nm wide. Nanoskin ACT Soft, like a paste, is designed to fill irregularities or recesses in the wound bed, and to absorb excess exudate from lesions by prolonging the used dressing's residence time and reducing the frequency of change.
