“…Cell adhesion plays an integral role in cell signaling and regulates a series of cellular events , such as cell migration, cell differentiation and cell survival. Research in this field appeals for techniques to characterize cell adhesion in order to better understand, control and optimize cell adhesion to various types of biomaterials . To this end, POA shows great potential after its successful application in the microelectronics industry as an accurate noncontact means of measuring and controlling bonding at the nanometer scale.…”

“…Ti serves as a light‐absorbing layer to favor the generation of CAPs that are used for imaging in this work. We also chose Ti for its broad applications in the biomedical field for implants and its great importance in understanding cell interaction with metallic biomaterials in vitro . The sapphire slab functions not only as a sample substrate but also, more importantly, as a heatsink to dissipate the possible laser heating, thereby protecting cells from any laser heating damage.…”

Advances in microscopy with new visualization possibilities often bring dramatic progress to our understanding of the intriguing cellular machinery. Picosecond optoacoustic micro‐spectroscopy is an optical technique based on ultrafast pump‐probe generation and detection of hypersound on time durations of picoseconds and length scales of nanometers. It is experiencing a renaissance as a versatile imaging tool for cell biology research after a plethora of applications in solid‐state physics. In this emerging context, this work reports on a dual‐probe architecture to carry out real‐time parallel detection of the hypersound propagation inside a cell that is cultured on a metallic substrate, and of the hypersound reflection at the metal/cell adhesion interface. Using this optoacoustic modality, several biophysical properties of the cell can be measured in a noncontact and label‐free manner. Its abilities are demonstrated with the multiple imaging of a mitotic macrophage‐like cell in a single run experiment.

“…Another area is biomedical, i.e. dental and orthopaedic implants, where LIPSS textured surfaces have been used to influence biocompatibility [6], cell proliferation [7] and also bacterial adhesion and biofilm formation [8,9]. Furthermore, LIPSS texturing of hard coatings has also been investigated for tribological applications [10].…”

Laser Surface Texturing of Polymers for Biomedical Applications

et al. 2018

Polymers are materials widely used in biomedical science because of their biocompatibility, and good mechanical properties (which, in some cases, are similar to those of human tissues); however, these materials are, in general, chemically and biologically inert. Surface characteristics, such as topography (at the macro-, micro, and nano-scale), surface chemistry, surface energy, charge, or wettability are interrelated properties, and they cooperatively influence the biological performance of materials when used for biomedical applications. They regulate the biological response at the implant/tissue interface (e.g., influencing the cell adhesion, cell orientation, cell motility, etc.). Several surface processing techniques have been explored to modulate these properties for biomedical applications. Despite their potentials, these methods have limitations that prevent their applicability. In this regard, laser-based methods, in particular laser surface texturing (LST), can be an interesting alternative. Different works have showed the potentiality of this technique to control the surface properties of biomedical polymers and enhance their biological performance; however, more research is needed to obtain the desired biological response. This work provides a general overview of the basics and applications of LST for the surface modification of polymers currently used in the clinical practice (e.g., PEEK, UHMWPE, PP, etc.). The modification of roughness, wettability, and their impact on the biological response is addressed to offer new insights on the surface modification of biomedical polymers.
