Special Issue Information

Dear Colleagues,

Due to manufacturing capability at micro- and nano-scales, lasers have emerged as versatile tools for fabricating innovative scaffolds and devices for tissue engineering, biomimetic delivery systems for local release, or lab-on-a-chip applications.

Herein, laser-based methods are introduced as emerging technologies for controlled surface modification and inorganic, organic and composite materials’ assembling. By modulating the irradiation conditions with thermo-physical properties of materials, new 2D nanoscale structures with improved biological properties can be fabricated. The laser processed biomimetic surface-cell interfaces are then evaluated as potential synergistic environments for tissue engineering and local release applications. Laser direct writing technologies are also innovative tools for fabricating microfluidic lab-on-a-chip devices with micro-scale dimensions and nano-scale features. Three-dimensional material configurations are used as potential biomimetic environments for evaluation of specific cellular behavior.

This Special Issue invites original contributions from authors in related areas of research, from surface structuring and functionalization using laser irradiation techniques to biomimetic 3D laser processing for biomedical applications such as: reconstruction of tissue-like architecture, controlled release of active biomolecules, study of cell behavior in 3D configurations or even construction of 3D tissue/organ models.

Abstract
This review is focused on the realization of liquid-repellent surfaces, inspired by two biological models: “dry” superhydrophobic leaves and “slippery” liquid-repellent carnivorous plants using ultrafast laser processing.

This review is focused on the realization of liquid-repellent surfaces, inspired by two biological models: “dry” superhydrophobic leaves and “slippery” liquid-repellent carnivorous plants using ultrafast laser processing. After a short introduction to a biomimetic development process, an overview of the laser-fabricated structures, which were intensively used for the realization of biomimetic “dry” and “slippery” liquid-repellent surfaces, is given. The influence of process parameters on the structure morphology is discussed. A summary of superhydrophobic and liquid-repellent modifications of different materials (metals, semiconductors, and polymers), including wettability characteristics and processing details, is provided. The technological applications of laser-structured liquid-repellent surfaces are discussed. Full article

This review investigates the capabilities of laser-based interferometric methods for producing structures with multiple-scaled surface features imitating natural examples. Firstly, laser interference lithography is used to produce hierarchical patterns with length-scales in the micrometer and sub-micrometer range. Different strategies are discussed to produce a wide variety of periodic arrays, depending on the number of resist lasers used as well as the way in which the exposure steps are organized. After that, periodic patterns are fabricated on polymers using ns laser pulses from an UV-laser system. Additionally in this case, multiple-scale patterns are produced by using different strategies. A similar approach is described to treat metallic surfaces of steel X6Cr17 and a titanium alloy Ti6Al4V. The geometry of the produced microstructures was characterized using scanning electron microscopy and confocal microscopy. Measurement of water contact angle is performed for both polymer and metallic surfaces. Full article

Biodegradable polymers have attracted increasing attention in tissue engineering and drug delivery systems owing to their high biocompatibility and biodegradability. Among the various methods for shape forming and modification of biodegradable polymers, laser processing has advantages in a dry processing approach that can process complex-shaped surfaces without using toxic chemical components. This review provides an overview of femtosecond laser processing of biodegradable polymers, especially in the last decade. The interaction mechanism of femtosecond laser pulse and biodegradable polymers, e.g., bond dissociation after laser irradiation, affects the degradable property of biodegradable polymers, which has the potential to control the degradation and sustainability of a structure. Applied studies on controlling cell behavior, tissue scaffolding, and drug release are also described. Full article
