Hydrogel microwells with light-controlled reversible closure
Qifei Ma, David Urban, Stefano Gabetti +8
We present a light-responsive hydrogel nanocomposite engineered into arrays of micrometer-scale wells that can be selectively and sequentially closed and re-opened via laser illumi…
Plasmonic nanopore to monitor in-pore chemistry
Weihong Wang, Shukun Weng, Ali Douaki +8
In solid-state nanopores, achieving reliable control over pore aperture opening and closing (gating) remains a major challenge. Gating can be driven by the applied voltage involvin…
UV-SERS monitoring of plasmons photodegradation of biomolecules on Aluminum platforms decorated with Rhodium nanoparticles
Yanqiu Zou, Luca Mattarozzi, Huaizhou Jin +13
In the search for novel nanostructured materials for UV plasmonics a limited number of choices can be done. Materials such as aluminum, rhodium, gallium and few others can be used.…
Plasmonic Janus particles: A perspective on optical manipulation and biomedical applications
Alemayehu Nana Koya, Anastasiia Sapunova, Nageswar Reddy Sanamreddy +8
The compositional asymmetry of Janus micro- and nanoparticles gives unprecedented opportunities to manipulate such composite particles with different stimuli to achieve enhanced op…
Dynamics of DNA-Templated Ultrafine Silver Nanowires Formation
Qifei Ma, Mauro Chinappi, Ali Douaki +10
Recent research on silver nanowires prepared on DNA templates has focused on two fundamental applications: nano-scale circuits and sensors. Despite its broad potential, the formati…
Application of Optical Tweezers in the Study of Emulsions for Multiple Applications
Qifei Ma, Huaizhou Jin, Xiaoxiao Shang +6
Emulsions are ubiquitous in everyday life and find applications in various industries. Optical tweezers (OTs) have emerged as the preferred method for studying emulsion dynamics. I…
