“…Another approach is to use focused plasma treatment from a dielectric barrier discharge jet, by confining the jet with glass capillaries as small as 100 μm in diameter, modifying regions up to 1.5 mm in diameter, even when using atmospheric low-flow-rate plasma. 65 This approach effectively localizes cell growth, which is beneficial for isolating and patterning cell populations. 66 The area modified by the plasma beam is not limited to the size of the striking plasma jet, as reactive species follow the gas flow profile away from the impingement point and modify the PS surface for some distance.…”

“…Treating 3D objects with plasma remains a challenge. To confine the treatment, immersion ionization or a confinement chamber at low (<100 Pa), 64 , 69 medium (∼1 kPa), 70 and atmospheric (∼100 kPa) pressures 55 , 65 , 71 have been used ( Fig. 5 ), reducing safety concerns brought with corrosive components.…”

Polystyrene (PS) has brought in vitro cell culture from its humble beginnings to the modern era, propelling dozens of research fields along the way. This review discusses the development of the material, fabrication, and treatment approaches to create the culture material. However, native PS surfaces poorly facilitate cell adhesion and growth in vitro. To overcome this, liquid surface deposition, energetic plasma activation, and emerging functionalization methods transform the surface chemistry. This review seeks to highlight the many potential applications of the first widely accepted polymer growth surface. Although the majority of in vitro research occurs on two-dimensional surfaces, the importance of three-dimensional (3D) culture models cannot be overlooked. The methods to transition PS to specialized 3D culture surfaces are also reviewed. Specifically, casting, electrospinning, 3D printing, and microcarrier approaches to shift PS to a 3D culture surface are highlighted. The breadth of applications of the material makes it impossible to highlight every use, but the aim remains to demonstrate the versatility and potential as both a general and custom cell culture surface. The review concludes with emerging scaffolding approaches and, based on the findings, presents our insights on the future steps for PS as a tissue culture platform.

Uniform Area Treatment for Surface Modification by Simple Atmospheric Pressure Plasma Treatment Technique

et al. 2019

The atmospheric pressure plasma jet (APPJ) has a merit to treat curved or 3D surface without using a ground electrode but nonetheless limits applications for expanding treatment area due to the localized ionization energy induced by the propagation along the direction of guided ionization waves. This paper proposes a uniform area treatment for surface modification based on the experimental case studies relative to variations of the APPJ structures, such as the number of array jets and guide-tube, including bluff-body (GB) system plus gas compositions. In these case studies, the current, infrared (IR), and optical emission spectrum (OES) are analyzed to investigate the factors affecting intensive glow-like plasma generation for uniform area treatment. Plasma-treated polyethylene terephtalate (PET) films are additionally examined to check the possibility of uniform area treatment for surface modification by using atomic force microscope (AFM), Fourier transform-infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and water contact angle (WCA). Only in case of three-array jets with GB system using Ar with O 2 gas, the intense glow-like plasma is observed to be produced widely in discharge space, thereby enabling the entire surface of PET films to be treated uniformly. In particular, the proposed APPJs are observed to generate more abundantly the reactive nitrogen species (RNS) ranging from 330 and 380 nm and the reactive oxygen species (ROS) at 777.4 and 844.6 nm. Furthermore, the plasma-treated PET film shows that the abundant RNS and ROS play a significant role in smoothening and changing its surface into hydrophilic surface. As a result, it is confirmed that the intense glow-like plasma generated broadly by the proposed APPJs can uniformly treat the entire surface of PET films. INDEX TERMS Atmospheric-pressure plasmas, glow-like discharge, plasma diagnostics, polymer PET film, surface treatment. I. INTRODUCTION Recently, atmospheric pressure plasma (APP) device has attracted attention as advantages of non-thermal (low temperature), dry process, and replacing of conventional expensive low-pressure plasma. It has been applied to various fields, such as a surface modification [1], [2], polymer synthesis The associate editor coordinating the review of this manuscript and approving it for publication was Bora Onat.

“…Além disso, outra vantagem desse processo é a pequena distância necessária entre a fonte do plasma e o material a ser tratado, o que facilita e viabiliza seu uso em grandes dimensões em setores industriais mantendo a eficiência e o baixo custo de energia [3,8]. Atualmente, os equipamentos que utilizam esta técnica englobam desde canetas para cicatrização [9,10], até equipamentos industriais de grande porte, que podem produzir grande quantidade de ozônio [3,11].…”

Apesar das inúmeras publicações a respeito da versatilidade da técnica de descarga por barreira dielétrica (DBD), principalmente em aplicações emergentes como descontaminação biológica e química, pouco se apresentou sobre a influência dos parâmetros de processos. No presente trabalho é analisada a influência dos parâmetros do processo sobre as espécies ativas do plasma formado quando ar é utilizado como atmosfera. Analisou-se a influência da distância e voltagem aplicada entre eletrodos, bem como a frequência do pulso aplicado. As análises das espécies foram realizadas diagnosticando o plasma por espectroscopia de emissão óptica (EEO). Esses resultados foram correlacionados com dados da potência consumida no processo de produção de plasma, obtidos a partir das figuras de Lissajous. O equipamento DBD utilizado possui sua máxima eficiência de produção de plasma atmosférico com a distância entre eletrodos fixada em 0,5mm Voltagem de 15 kV e frequência de 500 ou 600 Hz dependendo da espécie ativa que se queira em maior quantidade N2 357nm ou N2 337nm respectivamente .
