Near-Infrared Spectroscopy in Bio-Applications

open access: yesMolecules, 2020
Near-infrared (NIR) spectroscopy occupies a specific spot across the field of bioscience and related disciplines. Its characteristics and application potential differs from infrared (IR) or Raman spectroscopy.

Breakthrough Potential in Near-Infrared Spectroscopy: Spectra Simulation. A Review of Recent Developments

open access: yesFrontiers in Chemistry, 2019
Near-infrared (12,500–4,000 cm−1; 800–2,500 nm) spectroscopy is the hallmark for one of the most rapidly advancing analytical techniques over the last few decades.

A Systematic Comparison of Motion Artifact Correction Techniques for Functional Near-Infrared Spectroscopy

open access: yesFrontiers in Neuroscience, 2012
Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp. These artifacts can be very damaging to the utility of functional NIRS, particularly in challenging subject groups ...

A Systematic Review of the Impact of Physical Exercise-Induced Increased Resting Cerebral Blood Flow on Cognitive Functions

open access: yesFrontiers in Aging Neuroscience, 2022
Brain perfusion declines with aging. Physical exercise represents a low-cost accessible form of intervention to increase cerebral blood flow; however, it remains unclear if exercise-induced amelioration of brain perfusion has any impact on cognition.

Rapid measurement of polycyclic aromatic hydrocarbon contamination in soils by visible and near-infrared spectroscopy [PDF]

open access: yes, 2013
Polycyclic aromatic hydrocarbons (PAHs) are widely distributed organic pollutants. At petroleum contaminated sites, PAHs are often the key risk drivers because of their carcinogenicity. Assessing the risk of PAH at contaminated sites by conventional soil

Speeded near infrared spectroscopy (NIRS) response detection. [PDF]

open access: yesPLoS ONE, 2010
The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally delayed from the onset of the underlying neural activity. As a consequence, NIRS based brain-computer-interfaces (BCIs) and neurofeedback learning systems, may have a ...

Detection of the Degree of Natural Mildew of Camellia oleifera Fruit Using Visible/Near Infrared, Mid- and Short-Wave Near Infrared Spectroscopy [PDF]

open access: yesShipin Kexue, 2023
This study explored the feasibility of applying visible and near-infrared (400?1 000 nm), and mid- and short-wave near infrared (900?1 700 nm) spectroscopy for detecting Camellia oleifera fruit with different degrees of natural mildew.

Application of Near Infrared Spectroscopy in Cardiopulmonary Resuscitation

open access: yesXiehe Yixue Zazhi, 2023
With the rapid development of society, cardiac arrest has become a major public health problem worldwide. For cardiac arrest patients, the primary goal of cardiopulmonary resuscitation(CPR) is to ensure oxygen supply to the brain and prevent brain ...
