In this study, Graphite Oxide (GO) film with a 2-D structure was successfully synthesized via the Hummer method. The GO film was further reduced by hydrazine to form a few layers of graphene. The graphite oxide and reduced graphene oxide synthesized in this study were characterized by Scanning Electron Microscopy (SEM), Raman spectroscopy, and XRD analysis. A low-cost method using simple chemicals was employed to synthesize GO films with high conductivity on a large scale. The synthesized reduced graphene oxide can serve as an excellent material for various applications due to its lower cost and higher thermal, mechanical, and electrical conductivity. Large surface area graphene-based sensors and solar cells can efficiently replace expensive Carbon Nanotubes (CNTs).
Bladder cancer treatment with intravenous medication delivery has reasonable survival rates but modest therapeutic efficacy. Taking advantage of their superior diffusion and mixing capacities in urine compared to traditional pharmaceuticals or passive nanoparticles, self-propelled nanoparticles, also known as nanobots, have been proposed as a solution to the latter issue. Nonetheless, nothing is known about how well nanobots can translate into bladder cancer treatments. Here, urease-powered, radiolabelled mesoporous silica-based nanobots were evaluated in an orthotopic animal model of bladder cancer. Both in vivo and ex vivo findings showed increased accumulation of nanobots at the tumor location; positron emission tomography in vivo showed an eight-fold increase. The ex vivo tumor penetration by nanobots was validated by label-free optical contrast based on polarization-dependent scattered light-sheet microscopy of cleared bladders. Intravesically treatment was given to tumor-bearing mice. About 90% less tumor size was observed when radio-iodinated nanobots were used for radionuclide therapy, establishing nanobots as effective delivery nanosystems for bladder cancer treatment.
There are several classifications that describe the way materials function in the body. Devices that mimic a portion or function of the body in a safe, dependable, cost-effective, and physiologically appropriate way are made using biomaterials. Numerous tools and substances are now employed in the treatment of illness or injury, including everyday objects like tooth fillings, sutures, needles, catheters, plates, and so on. As time goes on, a synthetic substance that functions in close contact with live tissue or replaces a portion of a biological system might be summed up as a biomaterial. A biomaterial is described as "a systemically and pharmacologically inert substance designed for implantation within or incorporation with living things" by the Clemson University Advisory Board for Biomaterials. Materials, whether synthetic or natural, that may be utilized in any system that treats, enhances, or substitutes any organ, tissue, or bodily function for any length of time or on the other hand, a biological substance is one that is created by a biological system, like skin or an artery.
The realm of 3D printing is rapidly evolving, offering a wide range of options from typical thermoplastics to advanced graphene-based composites. This technology improves production efficiency and gives consumers more control over customizing products and specifications. However, alongside its transformative potential, 3D printing also presents challenges, such as potential impacts on manufacturing jobs and security issues. Since its modest beginnings in developing visualization models, 3D printing has evolved to transform the manufacturing of distinct devices, implants, tissue engineering scaffolds, and drug delivery systems. This paper explores the most recent progress in 3D printing materials, including smart materials, ceramics, electronics, biomaterials, and composites, emphasizing the significance of adapting to changing materials and product requirements. It delves into the complex connection between printing parameters and the characteristics of printed composite parts, providing new opportunities to improve the strength and functionality of 3D-printed components. This review highlights how 3D printing can be utilized in various industries, such as medical devices and explosives research, using materials such as titanium, aluminum, carbon fiber, and thermoplastic polyurethanes. With the continuous growth of the 3D printing field, it is essential to adopt new methods and materials to fully realize its impact on the future of manufacturing and product development.
Bioprinting has been a trending technology in recent years. It is a combination of engineering and biology. It can be used in the fields of tissue engineering and drug screening. It can be used to print 3D structures using 3D modeling software and to print with cultured cells. Bioink should have cells with the following characteristics: cell viability, cell differentiation, degradation, biocompatibility, and printability. Bioink contains biomaterials, living cells, and growth factors that are used to grow the cells. The replaced cells should possess chemical, physical, and mechanical properties. There are several methods to print biological organs, including microextrusion, inkjet bioprinting, and stereolithography.
