Nanochemical Cell-Surface Evaluation in Photothermal Spectroscopic Imaging of Antimicrobial Interactions in the Model System Bacillus subtilis and Vancomycin
The power of photothermal spectroscopic imaging to visualize antimicrobial interactions on the surfaces of individual bacteria cells has been demonstrated on the model system Bacillus subtilis and vancomycin...
PublicationsGenomic characterization of Staphylococcus aureus from small ruminant-mastitis in Sardinia, Italy
Background: Staphylococcal mastitis is a common disease of small ruminants causing major economic losses. The problem is particularly significant in the rural areas of the Mediterranean region, where almost...
PublicationsOn-Fiber 3D Nanoprinted Antiresonant Hollow-Core Waveguides for Integrated Optofluidics
Guiding light in hollow cores represents a major research direction in modern fiber optics, enabling numerous transformative applications. However, structural and fabrication constraints have hindered...
PublicationsHigh-Speed Interferometric Scattering Tracking Microscopy of Compartmentalized Lipid Diffusion in Living Cells
Lateral diffusion measurements have been -used to infer information about the nano-organization of membranes. We employed interferometric scattering (ISCAT) microscopy at an acquisition rate of 2 kHz to...
PublicationsGradient Optical Response of Au Ellipse Nanopillar Array via Anisotropic Pillar Heights: A Highly Tunable Plasmonic Material toward Biosensing Applications
An ordered multispectral array of Au coated ellipse nanopillars was successfully fabricated via laser interference and nanoimprint lithography. The fabricated plasmonic substrate features a gradient plasmonic...
PublicationsEvaluating large language model agents for automation of atomic force microscopy
Large language models (LLMs) are transforming laboratory automation by enabling self-driving laboratories (SDLs) that could accelerate materials research. However, current SDL implementations rely on rigid...
PublicationsDouble-layer silicon-based optical phased array transceiver based on cascaded phase control
Light detection and ranging (LiDAR) is of central importance for modern artificial intelligence (AI) assisted automated intelligent optical devices. Silicon-based optical phased arrays (OPAs) have attracted...
PublicationsTailored photoactivity of 2D nanosheets synthesized by electron irradiation of metal–organic Ru(II) monolayers
Two-dimensional materials gain significant interest for applications in light harvesting and sensing due to their unique properties and low dimensions. A key challenge is the introduction of specific functionalities...
PublicationsPoly(2-Oxazoline)-Based Polyphotoacids: Synthesis, SolutionBehavior, and Cellular Uptake of Multi-ResponsiveIntracellular Transporters
This work describes the first polymeric photoacids based on poly(2-oxazoline)s. The presence of 1-hydroxypyrene units—a photoacid that can increase its acidity upon blue light irradiation through excited-state...
PublicationsSuper-resolution near-infrared autofluorescence microscopy depicts melanin containing organelles of the retinal pigment epithelium in human donor eyes
Purpose: In the human retinal pigment epithelium (RPE), melanin localizes to melanosomes as well as melanolipofuscin. Changes in the organelles’ volumetric density may have different clinical implications,...
