Application of Low-Temperature Plasma Processes for Biomaterials (original) (raw)

Plasma Science and Technology - Basic Fundamentals and Modern Applications [Working Title]

2018

The interaction of plasmas and materials has a long history in the modification of condensed matter. Plasma-material interaction (PMI) can govern how low-temperature and high-temperature plasmas interact and modify materials surfaces. In magnetic fusion devices, PMI can also influence the operation of the fusion device. For example, incident energetic charged particle on fusion wall material surfaces can release target atoms via sputtering and can implant fuel particles in the lattice. Implanted energetic particles can mix fuel and influence recycling of fuel back to the plasma. Sputtered target atoms can become ionized in the magnetic sheath and re-deposit at the wall surface. The magnetic sheath will influence the energy and angular distribution of incident energetic particles and influence the implantation and release of fusion fuel.

Generation and Applications of Plasma (An Academic Review)

2018

Plasma being the fourth and most abundant form of matter extensively exists in the universe in the inter-galactic regions. It provides an electrically neutral medium of unbound negative and positive charged particles, which has been produced by subjecting air and various other gaseous mixtures to strengthen the electromagnetic field and by heating compressed air or inert gasses for creating negative and positive charged particles known as ions. Nowadays, many researchers are paying attention to the formation of artificial Plasma and its potential benefits for mankind. The literature is sparsely populated with the applications of Plasma. This paper presents specific methods of generation and applications of Plasma, which benefits humankind in various fields, such as in electrical, mechanical, chemical and medical fields. These applications include hydrogen production from alcohol, copper bonding, semiconductor processing, surface treatment, Plasma polymerization, coating, Plasma disp...

Critical Need for a National Initiative in Low Temperature Plasma Research

arXiv: Plasma Physics, 2020

In the white paper we describe a national program in Low Temperature Plasma (LTP). The program should take advantage of the research opportunities of 3 rapidly growing areas (nanomaterial plasma synthesis, plasma medicine, microelectronics). The main theme is to achieve a fundamental understanding of Low Temperature Plasmas as they are applied to these different applications. This understanding will allow U.S. industry to meet the challenges of international competition.

Symbiosis between low temperature plasma and high temperature chemistry

The influence of high temperature chemistry on plasma is not well recognized. Meanwhile, smart utilization of this interaction can substantially improve industrially important plasma chemical processes. Intensive chemical processes result in the formation of excited molecules and chemical ionization. These phenomena are most obvious for flames with good electrical conductivity and light emitted by excited molecules. Even if there is no chemical process but gas temperature is above the threshold of radical appearance, the reactions of radicals create electronically excited molecules. The appearance of these excited molecules without direct electron energy consumption stabilizes the discharge and reduces the required electron energy for ionization. When temperature becomes even higher and reaches the threshold of thermal ionization, the role of radicals in ionization processes becomes insignificant. Discharges can be classified as warm discharges if the discharge temperature is within the temperature range, in which the role of chemistry and/or heat in the discharge "life support" is comparable to that of the electric field.

Grand challenges in low temperature plasmas

Frontiers in Physics, 2022

Low temperature plasmas (LTPs) enable to create a highly reactive environment at near ambient temperatures due to the energetic electrons with typical kinetic energies in the range of 1 to 10 eV (1 eV = 11600K), which are being used in applications ranging from plasma etching of electronic chips and additive manufacturing to plasma-assisted combustion. LTPs are at the core of many advanced technologies. Without LTPs, many of the conveniences of modern society would simply not exist. New applications of LTPs are continuously being proposed. Researchers are facing many grand challenges before these new applications can be translated to practice. In this paper, we will discuss the challenges being faced in the field of LTPs, in particular for atmospheric pressure plasmas, with a focus on health, energy and sustainability.

Low temperature plasma processes for biomedical applications and membrane processing

Desalination, 2006

Low temperature plasma deposition and treatment processes can be successfully employed in order to modify surfaces of biomedical interest, as well as to improve membrane properties. In particular, plasma processes can be used to improve the adhesion, spreading and proliferation of cells at the surface of materials, to tune the hydrophilic/hydrophobic and non fouling properties, and to provide surfaces suitable for immobilizing molecules (catalysts, biomolecules, etc.).

The Challenge of Plasma Processing - Its Diversity

Cold gas plasma is used in many industries from aerospace to life sciences for permanent re-engineering of the molecular surface properties of polymers, elastomers, metals and ceramics to provide unique surfaces that do not affect the bulk properties of the material. Examples of applications are: corrosion resistance, etching, enhanced wear resistance, biocompatibility, adhesive bonding, altered wetting properties such as creation of either hydrophobic, oleophobic or hydrophilic surfaces, and providing unique vapor barrier or gas transport properties.
