Advanced remote focus control in multicore meta-fibers through 3D nanoprinted phase-only holograms
In this study, we present an unexplored approach for remote focus manipulation using 3D nanoprinted holograms integrated on the end face of multicore single-mode fibers. This innovative method enables...
PublicationsTracing the background-suppressed vibrational decay time of a molecular monolayer with time-resolved surface-enhanced broadband coherent anti-Stokes Raman scattering
The sensitivity of molecular spectroscopy based on surface-enhanced coherent anti-Stokes Raman scattering (SECARS) is limited by the spectrally overlapping background from nonresonant four-wave mixing...
PublicationsAttentuated growth factor signaling during cell death initation sensitizers membranes towards peroxidation
Cell death programs such as apoptosis and ferroptosis are associated with aberrant redox homeostasis linked to lipid metabolism and membrane function. Evidence for cross-talk between these programs is...
PublicationsCytotoxic and pro-oxidant profile of a photosensitive ruthenium nitrosyl candidate for NO delivery in healthy human fibroblasts
Ruthenium nitrosyl (Ru-NO) complexes are of interest as photoactive nitric oxide (NO) donor candidates for local therapeutic applications. NO plays a crucial regulatory role in skin homeostasis, concentration-dependently...
PublicationsPoly(dehydroalanine)-Based Hydrogels as Efficient Soft Matter Matrices for Light-Driven Catalysis
Soft matter integration of photosensitizers and catalysts provides promising solutions to developing sustainable materials for energy conversion. Particularly, hydrogels bring unique benefits, such as...
PublicationsSite-specific electronic structure of covalently linked bimetallic dyads from nitrogen K-edge x-ray absorption spectroscopy
A nitrogen K-edge x-ray absorption near-edge structure (XANES) survey is presented for tetrapyrido[3,2-a:2′ ,3′ -c:3′′,2′′-h:2′′′,3′′′ - j]phenazine (tpphz)-bridged bimetallic assemblies...
Publications1.8 mJ pulses at 1560 nm based on a 55 µm core pure-erbium-doped VLMA fiber
Despite the increasing demand for high-energy erbium lasers for LIDAR imaging applications, the scaling of the current Er-Yb co-doped technology is still hindered by a 1 µm parasitic emission. In this...
PublicationsAutofluorescence imaging guided needle-type Raman spectroscopy system for breast tumor margin assessment
A trajectory-tracked, near-infrared autofluorescence imaging guided, biochemical signature-projected needle-type Raman spectroscopy (TNBN-RS) system integrated on a medical cart was developed for rapid...
PublicationsHomogeneous large field-of-view and compact iSCAT-TIRF setup for dynamic single molecule measurements
Interferometric scattering microscopy (iSCAT) enables prolonged and high frame rate single particle tracking (SPT) for studying molecular dynamics. Typical iSCAT setups employ conventional widefield or...
PublicationsLighting the Path: Raman Spectroscopy’s Journey Through the Microbial Maze
The rapid and precise identification of microorganisms is essential in environmental science, pharmaceuticals, food safety, and medical diagnostics. Raman spectroscopy, valued for its ability to provide...
