The development of simple and versatile methods for the deposition of biocompatible coatings to protect or functionalize a range of materials with different shapes is an important challenge. In this study, a versatile, room‐temperature process is presented for the deposition of silk fibroin on different materials viz., glass, polyethylene terephthalate, Ti alloy, and poly(dimethylsiloxane). Coating with thin fibroin films is achieved using an atmospheric plasma torch, wherein a silk‐fibroin aerosol solution is used as the working gas. The method consists of two sequential processes: plasma modification of the surface, followed by plasma‐assisted deposition. This allows enhanced adhesion of the protein to the underlying surfaces, and the deposition even on non‐planar and flexible substrates. The deposited films are characterized by optical microscopy, atomic force microscopy, and scanning electron microscopy. Primary and secondary structures of the surface‐attached fibroin films are investigated by Fourier transform infrared spectroscopy. The proposed approach offers a tunable and controllable strategy for the controlled deposition of proteins on complex surfaces, for a wide range of biomedical and technological applications, including dentistry and bioelectronics.

“…Activating the TPE surface via oxygen plasma appears to promote the bonding of the Bisamino Silane molecules, leading to the creation of a highly reactive network of silane groups at the surface of the TPE. Through surface activation of the glass substrate via oxygen plasma, hydroxyl groups are created [ 38 ], which are then available to react with the silane groups from the activated TPE. This combination, followed by an incubation at 60 °C to promote bond strength, provides a robust bonding between TPE and glass ( Figure 2 B).…”

Facile Patterning of Thermoplastic Elastomers and Robust Bonding to Glass and Thermoplastics for Microfluidic Cell Culture and Organ-on-Chip

The emergence and spread of microfluidics over the last decades relied almost exclusively on the elastomer polydimethylsiloxane (PDMS). The main reason for the success of PDMS in the field of microfluidic research is its suitability for rapid prototyping and simple bonding methods. PDMS allows for precise microstructuring by replica molding and bonding to different substrates through various established strategies. However, large-scale production and commercialization efforts are hindered by the low scalability of PDMS-based chip fabrication and high material costs. Furthermore, fundamental limitations of PDMS, such as small molecule absorption and high water evaporation, have resulted in a shift toward PDMS-free systems. Thermoplastic elastomers (TPE) are a promising alternative, combining properties from both thermoplastic materials and elastomers. Here, we present a rapid and scalable fabrication method for microfluidic systems based on a polycarbonate (PC) and TPE hybrid material. Microstructured PC/TPE-hybrid modules are generated by hot embossing precise features into the TPE while simultaneously fusing the flexible TPE to a rigid thermoplastic layer through thermal fusion bonding. Compared to TPE alone, the resulting, more rigid composite material improves device handling while maintaining the key advantages of TPE. In a fast and simple process, the PC/TPE-hybrid can be bonded to several types of thermoplastics as well as glass substrates. The resulting bond strength withstands at least 7.5 bar of applied pressure, even after seven days of exposure to a high-temperature and humid environment, which makes the PC/TPE-hybrid suitable for most microfluidic applications. Furthermore, we demonstrate that the PC/TPE-hybrid features low absorption of small molecules while being biocompatible, making it a suitable material for microfluidic biotechnological applications.

Hydrophobic poly(methyl methacrylate)/silica layers on the glass support activated with plasma were obtained. Wettability was investigated from the contact angle measurements and surface free energy estimation by means of using contact angle hysteresis approach. The thermal analysis of poly(methyl methacrylate)/silica films was conducted on a STA 449 Jupiter F1, Netzsch in temperature range of 30-950 C. It was found that the thermal stability of the poly(methyl methacrylate)/silica films decreases with increasing poly(methyl methacrylate) amount in the sample. Morphology of the obtained nanocomposites was investigated by means of scanning electron microscopy. The addition of silanized silica to the poly(methyl methacrylate) solution leads to obtaining the film with more hydrophobic properties, the contact angle value over 90 , and the apparent surface free energy lower than 30 mJ/m 2 . The most hydrophobic film was obtained in the case of silica with Â ¼ 0.63 (Â -surface fraction coverage with trimethylsilyl groups). Silica particles were well dispersed in the polymer solution which was confirmed by the scanning electron microscopy analysis.
