Photoluminescence: Applications01:14

Photoluminescence: Applications

1.3K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Photoluminescence: Fluorescence and Phosphorescence

5.5K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Variables Affecting Phosphorescence and Fluorescence01:26

Variables Affecting Phosphorescence and Fluorescence

2.6K
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Fluorescence and Phosphorescence: Instrumentation

2.0K
Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.

Photoelectric Effect02:26

Photoelectric Effect

41.3K
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...

Labeling DNA Probes03:31

Labeling DNA Probes

9.8K
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Area of Science:

  • Nuclear Medicine
  • Pediatric Oncology
  • Radiopharmaceutical Therapy

Background:

  • Neuroblastoma is a pediatric cancer often treated with 131I-meta iodobenzylguanidine (131I-mIBG).
  • 131I-mIBG therapy involves radioactive isotopes, necessitating radiation safety protocols.
  • Radioactivity in patient secretions post-treatment requires careful management.

Purpose of the Study:

  • To underscore the significance of radiation safety measures.
  • To emphasize the need for proper handling of radioactive secretions after 131I-mIBG treatment.
  • To illustrate potential contamination routes from patient secretions.

Main Methods:

  • A case study of a 4-year-old girl with stage 4 neuroblastoma is presented.
  • Single-photon emission computed tomography (SPECT) was used to identify radioactivity.
  • Radioactivity was detected on the patient's comfort blanket, specifically where she had been sucking.

Main Results:

  • Significant radioactivity was confirmed in the patient's comfort blanket.
  • This finding indicates that patient secretions can transfer radioactivity to external objects.
  • The patient's secretions remained radioactive for a period following the diagnostic scan.

Conclusions:

  • Previous studies noted 131I-mIBG uptake in salivary glands.
  • This case highlights that patient secretions remain radioactive post-treatment.
  • Reinforces the critical importance of meticulous handling of radioactive secretions to prevent contamination and ensure safety.
