Absorption and emission properties of thulium doped glasses in optical fibers
Optical properties of Tm-doped fibers based on different host glass materials, silica and yttrium-aluminum-garnet (YAG), prepared with different technologies, are studied. We show that crystal-derived...
PublikationenDevelopment and performance validation of an affordable and portable high-resolution darkfield polarization-sensitive multispectral imaging microscope for the assessment of radiation dermatitis and fibrosis
Radiation therapy (RT) is widely used for cancer treatment but is found with side effects of radiation dermatitis and fibrosis thereby calling for timely assessment. Nevertheless, current clinical assessment...
PublikationenPolarity dependent predictable and random resistive switching in forming-free unipolar memristors
Polycrystalline, hexagonal HoMnO3 thin films sandwiched between an un-patterned Pt/Ti bottom electrode and a circularly patterned Al top electrode reveal forming-free, polarity dependent predictable and...
PublikationenA comparative study of statistical, radiomics, and deep learning feature extraction techniques for medical image classification in optical and radiological modalities
Feature extraction in ML plays a crucial role in transforming raw data into a more meaningful and interpretable representation. In this study, we thoroughly examined a range of feature extraction techniques...
PublikationenDevelopment of a label-free, functional, molecular and structural imaging system combining optical coherence tomography and Raman spectroscopy for in vivo measurement of rat retina
In vivo access to molecular information of retinal tissue is considered to play a critical role in enabling early diagnosis of ophthalmic and neurodegenerative diseases. The current gold standard of retina...
PublikationenA multiplexing immunosensing platform for the simultaneous detection of snake and scorpion venoms: Towards a better management of antidote administration
Envenomation accidents are usually diagnosed at the hospital through signs and symptoms assessment such as short breath, dizziness and vomiting, numbness, swilling, bruising, or bleeding around the affected...
PublikationenFrontiers in laccase nanozymes-enabled colorimetric sensing: A review
In recent years, nanozyme-based analytics have become popular. Among these, laccase nanozyme-based colorimetric sensors have emerged as simple and rapid colorimetric detection methods for various analytes,...
PublikationenProtected memristive implementations of cryptographic functions
Memristive technology mitigates the memory wall issue in von Neumann architectures by enabling in-memory data processing. Unlike traditional complementary metal-oxide semiconductor (CMOS) technology, memristors...
PublikationenCharacterizing Metabolic Shifts in Septic Murine Kidney Tissue Using 2P-FLIM for Early Sepsis Detection
In this study, thin mouse kidney sections from healthy mice and those infected, leading to acute and chronic sepsis, were examined with two-photon excited fluorescence lifetime imaging (2P-FLIM) using...
PublikationenRapid Colorimetric Detection of Sulfite in Red Wine Using Alginate-Copper Laccase Nanozyme with Smartphone as an Optical Readout
Compared with the conventional analytical methods, nanozyme-based colorimetric sensors offer simpler and more accessible solutions for point-of-need food safety monitoring. Herein, Alginate-Cu (AlgCu)...
