“…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].…”

“…Their generation can be tailored depending on irradiated materials, laser wavelength, beam polarization, fluence and number of pulses [7]. More complex LIPSS morphologies, such as diamond-shaped LSFL, were generated in multi-step processes requiring several crosspolarized scans of the surface [8]. Other single-scan processes, involving radial polarized beam, dynamic rotation of the polarization or double cross-polarized pulses, could induce complex but controlled LIPSS morphologies such as rhombic shapes [9,10].…”

Considering the attractive surface functionalities of springtails (Collembola), an attempt at mimicking their cuticular topography on metals is proposed. An efficient single-step manufacturing process has been considered, involving laser-induced periodic surface structures (LIPSS) generated by near-infrared femtosecond laser pulses. By investigating the influence of number of pulses and pulse fluence, extraordinarily uniform triangular structures were fabricated on stainless steel and titanium alloy surfaces, resembling the primary comb-like surface structure of springtails. The laser-textured metallic surfaces exhibited hydrophobic properties and light scattering effects that were considered in this research as a potential in-line process monitoring solution. The possibilities to increase the processing throughput by employing high repetition rates in the MHz-range are also investigated.
