Electrospinning
We investigate the design and fabrication of functional nanofibrous materials through electrospinning: a versatile method for producing fibers with tailored architecture, composition, and properties. Using biocompatible and biodegradable polymers, we develop core–shell, porous, and composite fibers optimized for specific biomedical functions. Our activities include the creation of photo-activated nanoplatforms enriched with plasmonic nanoparticles for on-demand and sustained drug release, light-triggered antibacterial materials, and reusable face masks with photothermal decontamination capability. We have competencies in designing injectable microscaffolds with femtosecond laser-induced porosity, as well as eco-friendly electrospun patches that provide moisturizing, antibacterial, and healing effects.
Laser structuration
We engineer microscale surface topographies with precisely controlled laser energy to tailor material behavior for custom applications. The spectrum ranges from laser-induced micro-texturing, drilling, to surface modification, and material shape adjustment. We use beam shaping to pattern large areas of materials, as well as write microfluidic channels directly in the glass via micromachining and laser-assisted chemical etching. In the field of polymeric surfaces, we possess competencies in process development, laser post-processing functionalization, including the tuning of porosity and wettability properties, as well as comprehensive characterization.
3D printing
We develop advanced 3D printing strategies for the fabrication of functional materials and antibacterial wound dressings. Our research combines additive manufacturing with nanotechnology, enabling the precise control of structural, mechanical, and biological properties. We design and optimize bio-inks and composite materials that integrate polymers, nanoparticles, and biological agents to achieve tunable functionalities. By coupling 3D printing with smart materials, we fabricate platforms for regenerative medicine, drug delivery, and bioelectronic applications.
