LIBSTechnical principles and advantages
Application case:
1. LIBSThe application of technology in cancer detection:
CEITECThe Lightigo research team at Brno University of Technology is conducting research on skin cancer detection using LIBS technology - the elemental composition of cancerous cells is different from that of normal cells, so LIBS technology is used to detect the elemental characteristics of tumor tissue for medical diagnosis.
This image is quoted from the news article of this interview on the Czech Radio website
2020On January 24th of the year, Czech radio released an interview with the Lightigo team at the Laser Spectroscopy Laboratory of Brno University of Technology. Pavel Po, the project leader of LightigořízkaSpeaking of: "LIBS measurement can obtain a series of element distribution images, helping pathologists to diagnose as soon as possible. Large tumors are easy to detect, but LIBS technology will be very useful for small satellite tumors that are difficult to detect
2. Comparative study on the enrichment and stress effects of Cd quantum dots and Cd ions in Cd salt on floating duckweed using LIBS technology
Floating duckweed（Lemna minor L.）It is an indicator species of metal element environmental pollution and a model organism commonly used for research on metal toxicity and enrichment. In this case, the AtomTrace team applied LIBS technology to perform element distribution mapping on floating duckweed, comparing the enrichment patterns of Cd elements in floating duckweed between Cd salts and QDs; And traditional ICP-OES technology was applied to measure the content and enrichment of different Cd containing compounds in floating duckweed; Simultaneously applying TEM method to investigate the enrichment location of QDs - on the surface of duckweed, inside cells, or within plant tissues.
CdMapping images of leaf elements in duckweed treated with quantum dots and Cd salts
Experimental conclusion:
§ CdCl2There is no difference in the impact of Cd QDs pollution on the distribution of Cd elements on the surface of duckweed leaves;
§ Different concentrations have no significant effect on the distribution of Cd element on the surface of duckweed leaves;
§ Three cadmium containing compounds (CdCl) in the experiment2、The concentration of MPA QDs and GSH QDs increased, and the LIBS detection signal also increased accordingly;
§ The enrichment of Cd element at the stem node is significantly higher than that in other tissues
