Advanced Manufacturing using Ultrafast Laser Direct Writing :

‣ Maskless & fast fabrication using ultrafast (femtosecond) laser direct writing

• Ablation : 2D surface patterning and texturing

• Multi-photon polymerization : 3D Nanoscale fabrication and printing

‣ Three-dimensional (3D) artificial tissue scaffold fabrication for disease modelling :

• 3D artificial cardiac tissue from human induced pluripotent stem (hiPS) cells

• in vitro drug screening platform fabrication for disease diagnosis (e.g., cardiac electrophysiology)

‣ 3D Microfluidic channel fabrication using FLICE (Femtoseond Laser Induced Chemical Etching)

• 3D microfluidics channel for fluid mixing enhancement

• Single cell/molecular detection and analysis (DNA, enzyme etc.)

• Control of drops and biomaterials in nanofluidics Systems

Biomechanics in Cellular / Molecular Applications :

‣ Cellular mechanics : Control of cell adhesion / migration on the 2D/3D nanoscale platform

(e.g., Angiogenesis / metastasis of tumor cell on toxic condition)

‣ Mechanotrasduction

Flexible Electrode Fabrication based on Green Synthesis and Sintering :

‣ Metal (conductive) pattering on flexible substrate using bio-inspired materials

Scalable laser-assisted 3D printing of nanomaterials :

‣ Enhancement of block-co-polymer direct self-assembly in nanoscale 3D confined structure

• Smart photonic system (e.g., photonic crystal) fabrication

Visualization of Fluids :

‣ Particle Image Velocimetry (PIV) / Particle Tracking Velocimetry (PTV)

‣ Particle tracking near the solid surface
