Enhanced terahertz near-field nanoscopic imaging for label-free assessment of ovarian cancer cells: a preliminary study [0.03%]
Wei Mao,Dan Zhao,Zhaomin Peng et al.
Wei Mao et al.
This preliminary study aimed to evaluate the feasibility of enhanced terahertz (THz) scattering-type scanning near-field optical microscopy (s-SNOM) for the label-free, nanoscale imaging of ovarian cancer cells. Leveraging an advanced THz s...
MW-FlexNIRS: wearable, low-cost, LED-based, multi-wavelength NIRS oximeter for cytochrome c oxidase recovery in neonates [0.03%]
Nikola Otic,Mitchell B Robinson,Kuan-Cheng Wu et al.
Nikola Otic et al.
We present MW-FlexNIRS, a wearable, low-cost, LED-based, multi-wavelength near-infrared spectroscopy (NIRS) system designed for continuous monitoring of cerebral oxygenation and metabolic dynamics in neonates. The device extends the origina...
Fluorescence properties of methylene blue conjugated to normal/cancerous human tissues for spectral discrimination of breast cancer stages (I-IV) [0.03%]
Romina Khoshnevisan,Parviz Parvin,Fatemeh Ramezani et al.
Romina Khoshnevisan et al.
Laser-induced fluorescence (LIF) spectroscopy is utilized to differentiate normal/malignant breast cells/tissues and classify cancer stages, using the biocompatible methylene blue (MB) fluorophore. Cancerous cells (MCF-7) conjugated with MB...
Green channel-informed collaborative filtering for high-fidelity laser speckle contrast imaging in dual-display laparoscopy [0.03%]
Yadi Xue,Jialin Liu,Wei Zhou et al.
Yadi Xue et al.
The dual-display laparoscopic imaging system (DLIS), which integrates laser speckle contrast imaging (LSCI) with white-light RGB mode, enhances surgical decision-making during minimally invasive procedures. However, motion artifacts and dyn...
Peripheral refractive errors in pseudophakic eyes: in vitro evaluation and optical simulation [0.03%]
D Romashchenko,A Del Aguila,M State et al.
D Romashchenko et al.
We present a systematic assessment of peripheral refractive errors in pseudophakic eyes. Optical bench measurements were performed using a physical eye model to characterize the peripheral cylinder of eight different intraocular lens (IOL) ...
Characterization of a fiber-coupled SPAD camera system for deep-tissue blood-flow measurement using diffuse correlation spectroscopy [0.03%]
Christopher H Moore,Michael A Wayne,Arin C Ulku et al.
Christopher H Moore et al.
Diffuse correlation spectroscopy (DCS) is a promising technique for noninvasive measurement of blood flow, especially cerebral blood flow, where other noninvasive techniques have shortcomings. Conventional DCS often requires multiple simult...

Rupak Bhakta et al.
Understanding cell-nanoparticle interaction is crucial for advancing nanoparticle-based medicine. Doppler imaging techniques, such as Doppler Optical Coherence Tomography (DOCT), have been widely used for dynamic imaging. However, conventio...
Qualitative and quantitative assessment of ex vivo human brain tumors using quantitative oblique back-illumination microscopy (qOBM) [0.03%]
Srinidhi Bharadwaj,Paloma Casteleiro Costa,Caroline Serafini et al.
Srinidhi Bharadwaj et al.
Accurate intraoperative diagnosis of brain tumors is critical for improving patient outcomes, yet current histopathology is time-consuming and performed outside the operating room. We investigate the use of quantitative oblique back-illumin...
