Liquid biopsy in cancer: Technical challenges and clinical applications
The development of blood-based, tumor-specific biomarkers called real-time liquid biopsy such as circulating tumor cells (CTCs) have made significant advances over the last years in cancer research.
Highly-sensitive liquid biopsy assays have been developed and are applied to detect minimal residual disease, to get prognostic information and to monitor therapy efficiency.
In my talk, I will present the new EPIDROP technology that detect viable CTCs. It allows the enumeration/characterization of all CTCs, and gives information on their functionality at the single cell level and also on their drug resistance profile in a few hours: developing an oncogram for the real-time follow-up of resistance against chemotherapy or immunotherapy is urgently needed.

Direct-writing of advanced nano-superconductors and devices using Focused Ion Beams
Superconductors are dissipationless carriers of electric current and provide macroscopic, and thus robust, quantum coherence. To achieve the required performance employed in applications as magnetic sensors, nowadays bulk superconductors frequently need nanoscale engineering. Interestingly, when these materials are reduced to the nanoscale becoming nano-superconductors, novel exciting physical phenomena emerge. This has encouraged the study of their performance in the three dimensions as key elements that would be implemented into superconducting circuits. Nevertheless, the fabrication and characterization of nano-superconductors in the three dimensions are still challenging. Here, I introduce a direct-write nanolithography method based on focused ion beam technologies to fabricate at-will advanced nano-superconductors. Particularly, I have prepared superconducting W-C nanostructures in the three dimensions by decomposing tungsten hexacarbonyl molecules with a highly-focused He+ or Ga+ ion beam.

Advancing the photolithography for more Moore
The steady shrinkage of the semiconductor devices in the last five decades, as predicted by Moore’s law, has changed our daily lives. This progress was possible through advancements in photolithography. Extreme ultraviolet (EUV) lithography at 13.5 nm wavelength is the manufacturing method for high-volume semiconductor manufacturing at 7 nm technology node and below. To enable future progress, many challenges lie ahead. In addition to the optical resolution, other limitations are already emerging, such as photon shot noise, mask 3D effects, and, not the least, resist materials. In this presentation, some of these issues will be addressed, and potential solutions are proposed.

Design Strategy for Mechanically Transformative Electronics, Sensors, and Implantable Devices
Conventionally, electronics are constructed with static form factors to serve targeted applications. For examples, emerging soft wearable electronics are designed to allow dynamic accommodation of applied stress to maximize user comfort when integrated with the body. In contrast, rigid electronics are built for tabletop or handheld uses based on their solid interfaces that ease user handling. To leverage advantages of both rigid and soft electronics, we developed a new class of electronics that can reconfigure their shape, flexibility and stretchability for desired purposes. This talk will introduce the concept, materials, and operation principle of transformative electronics with applications in wearables, implantables, and sensors.

Acoustic isolation of extracellular vesicles - From uL/min to mL/min
Isolation of nanobioparticles from suspension commonly requires extended ultracentrifugation and manual handling protocols. Microfluidics in combination with acoustics have in more recent years opened new avenues to nanoparticle manipulation. Acoustic seed trapping is a technology that utilizes inter particle forces derived from sound scattered at particles in suspension and enables submicron particle enrichment. In biomedicine extra cellular vesicles (EV) (i.e. submicrometer vesicles, shed from cells) gain a lot of attention as potential carriers of biomarkers. We have previously pioneered the development of acoustic seed trapping of EVs in biofluids (≈10-100 uL samples) for biomarker analysis. In order to broaden the applicability of acoustic seed trapping, processing of larger sample volumes are needed. We now show the upscaling of acoustic EV isolation in urine from the 10-100 uL/min to mL/min range and demonstrate a 40X capacity increase of seed particles. The capacity increase enabled rapid isolation of urine EVs for subsequent mapping of differential proteome profiles of urine vs. the urine EV fraction as monitored by mass spectrometry. The current EV isolation platform now provides a rapid route to defined EV-based sub proteomes in biofluids.

Silicon based Metalenses for tight focusing of light
Metasurfaces are ultrathin-film optical elements that can manipulate the amplitude, phase, and polarization of light. The need to minaturise optical elements has generated a significant research effort on the realisation of flat structures to focus light such as subwavelength gratings and metamaterials. To date, most of these structures manipulate a linearly polarised incident beam, whereas the use of radially or azimuthally polarised light offers important advantages. In this work, we use metasurfaces to simultaneously convert linearly polarized incident light into an azimuthally polarized optical vortex and focuses the at a distance approximately equal to the wavelength of the incident light.

Energy-selective plasmonic nanoreactors
Plasmonic resonances can concentrate light into exceptionally small volumes, approaching the molecular scale. The extreme light confinement provides an advantageous pathway to probe molecules at the surface of plasmonic nanostructures with highly sensitive spectroscopies, such as surface-enhanced Raman scattering. Unavoidable energy losses associated with metals, which are usually seen as a nuisance, carry invaluable information on energy transfer to the adsorbed molecules through the resonance linewidth. We measured a thousand single nanocavities with sharp gap plasmon resonances that spanned the red to near-infrared spectral range and used changes in their linewidth, peak energy and surface-enhanced Raman scattering spectra to monitor the energy transfer and plasmon-driven chemical reactions at their surface. Using methylene blue as a model system, we measured shifts in the absorption spectrum of molecules on surface adsorption and revealed a rich plasmon-driven reactivity landscape that consists of distinct reaction pathways that occur in separate resonance energy windows.

Dynamic metaphotonics for structural colors and holographic displays
Flat optics, which is realized by the artificially created two-dimensional material platform called optical metasurfaces, is currently undergoing a science-to-technology transition. A representative example includes a flat and ultra-compact metalens, which has huge potential for replacing conventional bulky and heavy optical lens. However, ‘real-time’ active operations of those flat optical devices have remained unresolved yet. To resolve such a grand challenge, we propose two approaches to realize dynamic metaphotonic devices using multiple light properties and tunable materials. We believe such dynamic metaphotonic devices will further accelerate real-life applications such as video holographic-displays, full-color high resolution displays, focus-tunable metalenses and LiDARs.

Reusable Millimeter Size Bone Tissue Replicas With Sub-15 nm Feature Size on A Biocompatible Polymer
The ability to replicate the microenvironment of biological tissues creates unique biomedical possibilities for stem cell applications. Current fabrication methods are limited by either the control on feature size and shape, or by the throughput and size of the replicas. Here, a novel platform is reported that combines thermal scanning probe lithography (tSPL) with innovative methodologies for the low-cost and high-throughput nanofabrication of large area quasi-3D bone tissue replicas with high fidelity, sub-15 nm lateral precision, and sub-2 nm vertical resolution . This bio-tSPL platform features a biocompatible polymer resist that withstands multiple cell culture cycles, allowing the reuse of the replicas, further decreasing costs and fabrication times. The as-fabricated replicas support the culture and proliferation of human induced mesenchymal stem cells, which display broad therapeutic and biomedical potential. Furthermore, it is demonstrated that bio-tSPL can be used to nanopattern the bone tissue replicas with amine groups, for subsequent tissue-mimetic biofunctionalization. The achieved level of time and cost-effectiveness, as well as the cell compatibility of the replicas, make bio-tSPL a promising platform for the production of tissue-mimetic replicas to study stem cell-tissue microenvironment interactions, test drugs, and ultimately harness the regenerative capacity of stem cells and tissues for biomedical applications.

The other is piezoelectric disk gyroscope with lithium niobate. Because of its high electromechanical coupling coefficient and high quality factor, higher performance is expected. We have demonstrated gyroscope operation using 155°-Y-cut wafer for mode matching of two wineglass modes.
