Biomolecular layer thickness evaluation using White Light Reflectance Spectroscopy

Microelectronic Engineering, 2010
A White Light Reflectance Spectroscopy (WLRS) methodology is applied in the evaluation of the effectiveness of biomolecules immobilization onto solid surfaces as well as their subsequent reaction with counterpart biomolecules via measuring the respective layers thickness.

Non-Destructive Characterization of Selected Types of Films and Other Layers via White Light Reflectance Spectroscopy (WLRS)

Micro, 2022
In this work, we consider White Light Reflectance Spectroscopy (WLRS) as an optical methodology for the accurate, fast and non-destructive measurement of film thickness in the 1 nm to the 1 mm range and for applications that include microelectronics, photonics, bioanalysis and packaging.

Multiplexed mycotoxins determination employing white light reflectance spectroscopy and silicon chips with silicon oxide areas of different thickness

Biosensors and Bioelectronics, 2020
Biosensing through White Light Reflectance Spectroscopy (WLRS) is based on monitoring the shift of interference spectrum due to the binding reactions occurring on top of a thin SiO2 layer deposited on a silicon chip. Multi-analyte determinations were possible through scanning of a single sensor chip on which multiple bioreactive areas have been created.

A White Light Reflectance Spectroscopy Label-Free Biosensor for the Determination of Fungicide Carbendazim

The 1st International Electronic Conference on Biosensors, 2020
Carbendazim is a systemic, broad-spectrum benzimidazole-type fungicide effective against fungi that compromise the safety/quality of food products (fruits, vegetables, field crops, etc.). Though carbendazim constitutes a major environmental pollutant, hazardous for humans and animals and has been banned in most of European Union and USA, many countries

Detecting head and neck lymph node metastases with white light reflectance spectroscopy; a pilot study [PDF]

Oral Oncology, 2021
A challenge in the treatment of patients with head and neck cancer is the management of occult cervical lymph node (LN) metastases. Single-fiber reflectance (SFR) spectroscopy has the potential to detect physiological tissue changes that occur in a positive LN. This pilot study aimed to investigate whether SFR spectroscopy could serve as an alternative

Real-time label-free detection of complement activation products in human serum by white light reflectance spectroscopy [PDF]

Biosensors and Bioelectronics, 2009
We present a label-free, real-time sensor based on white light reflectance spectroscopy for quantitating the complement activation product C3b and its metabolites as a biomarker in human serum. Our novel sensor allows real-time monitoring of biomolecular reactions (in this case, antigen-antibody reactions) taking place on a reflective surface within a ...

On the optical properties of monoclinic Na3AlF6 and Na3AlF6:Mn4+

Optical Materials: X, 2023
Mn4+ activated luminescent materials have attracted much attention as colour converters for light sources and displays. In particular, alkali metal hexafluorometallates, such as K2SiF6:Mn4+ or K2TiF6:Mn4+, emit light in the red spectral region if pumped ...

White Light Reflectance Spectroscopy as a Novel and Noninvasive Method for in Situ Wetting Monitoring in Membrane Distillation

Desalination, 2023
Wetting, in membrane distillation (MD), is a major drawback appearing as a dynamic mechanism consisting of multiple stages. Normally, the liquid-air interface is placed on top of the membrane surface and pores are only occupied with vapor. If liquid starts to penetrate, surface wetting is followed by partial wetting that develops until the fully wetted
