Application, Case, Applications & Solutions

1. Life science application programs and cases

The CEITEC/AtomTrace LIBS research team has long been concerned with the application of LIBS technology in the life sciences including biomedical applications.

In 2005, Dr. Jozef Kaiser (Scientific Director of Atomtrace, Professor of Brno University, Head of Laser Spectroscopy Laboratory, Director of CEITEC Department of Physical Properties and Surface Science) published "Mapping of the metal intake in" in the European Physical Journal. Plants by large-field X-ray microradiography and preliminary feasibility studies in microtomography" (Eur. Phys. J. D 32, 113-118); in 2006, LIBS femtosecond laser spectroscopy was used to analyze plant samples of iron and manganese. The distribution of the elements and the first two-dimensional distribution of the complete leaf iron elements (see the image to the right), and published "Femtosecond laser spectrochemical analysis of plant samples" (Laser Phys.Lett.3, No.1, 21-25, 2006 )

From 2007 to 2010, the research team represented by Dr. Kaiser used μCT and femtosecond laser induced breakdown spectroscopy (LIBS) and LA-LCP-MS techniques to study the absorption and accumulation of heavy metals in sunflower and other plant tissues. Analysis, published papers:

1) Monitoring of the heavy-metal hyperaccumulation in vegetal tissues by X-ray radiography and by Femto-second laser induced breakdown spectroscopy. Microscopy research and technique 70: 147-153, 2007;

8) Determination of plant thiols by liquid Chromatography Coupled with Coulometric and Amperometric Detection in Lettuce by lead (II) ions. Electroanalysis 22 No.11:1248-1259, 2010

The CEITEC/Atomtrace LIBS research team not only used LIBS technology to make complete leaf element distribution maps, but also used LIBS technology to combine with micro-CT (μCT) for 3D chemical imaging construction. The above research results have established the leading position of LIBS technology in the laser spectroscopy laboratory represented by Dr. Kaiser and others in the field of global life and environmental science applications.

The left picture shows the micro-CT of the root section of the sunflower, and the right picture shows the distribution of the lead metal in the sunflower root (from J. Kaiser et al., 2007).

The left picture shows the heavy metal pollution model, and the right picture shows the two-dimensional distribution of lead and magnesium concentrations in the leaves of corn, sunflower and lettuce LIBS.

In 2010, the laser spectroscopy laboratory represented by Kaiser used LIBS technology combined with μCT technology to study and analyze the distribution of spine bone elements including Ca, Al, P, Na, etc. of snake deformity osteitis, and published "Investigation of The osteitisdeformans phases in snake vertebrae by double-pulse laser-induced breakdown spectroscopy" (Anal. Bioanal. Chem. 398:1095-1107, 2010)

The picture above shows the snake spine μCT, the picture below shows the snake's normal vertebrae (a) and pathological vertebrae (b) two-dimensional distribution of calcium and phosphorus.

The laboratory research team also studied the application of LIBS technology in paleontology and archaeology. The following is the results of prehistoric animal teeth research and analysis (see: Multielemental analysis of prehistoric animal teeth by laser-induced breakdown spectroscopy and laser ablation inductively coupled Applied mass spectrometry. Applied Optics 49 No. 13: 191-199, 2010), this study is equally important for the study of annual ring element distribution and environmental change.

Prehistoric animal tooth Sr/Ca and Sr/Ba profiles were performed using LIBS technology and LA-LCP-MS techniques, respectively.

The bone picture shows the annual ring clearly (dark color for winter and white for summer)

In 2012, Dr. Kaiser and others published a review article "Trace elemental analysis by Laser-induced breakdown spectroscopy---biological applications" based on years of research and peer research (Surface Science Report 67:233-243, 2012)

The laboratory also used LIBS technology to conduct a large number of studies on algae (see "Liquid LIBS Elemental Analysis Application Cases and Protocols" later) and published a review article in 2014 "Algal biomass analysis by laser-based analytical techniques---a Review" (Sensor 14, 2014)

2. Geology and mineral application

The CEITEC/Atomtrace Laser Spectroscopy Laboratory has conducted extensive research on the application of LIBS in geology and mineral resources. In 2014, "Two dimensional elemental mapping by laser-induced breakdown spectroscopy" (Spectroscopy Europe 26 No. 6: 6-10, In the 2014 academic paper, the surface element distribution of arsenic platinum ore, chalcopyrite Pt, Pb, Ni, etc. was constructed in 2D and even combined with μCT.

Uranium is the most promising source of energy for humans. The in situ detection of the presence or absence of uranium is extremely important. The main challenge of uranium detection is its complex spectral emission and high-density spectral curves – even beyond the general spectrometer detection capabilities. The CEITEC laser spectroscopy laboratory used LIBS technology to measure and analyze sandstone uranium deposits through ANN (artificial neural network) information processing technology and PCA (principal component analysis).

3. Liquid (aqueous suspension) LIBS elemental analysis

As early as 2000, Dr. OtaSamek and Dr. Jozef Kaiser of the Laser Spectroscopy Laboratory of Brno University of Technology published "Application of laser-induced breakdown spectroscopy to in situ analysis of liquid samples" (Opt. Eng. 39(8) 2248- 2262, 2000). In 2012, the CEITEC Laser Spectroscopy Laboratory Research Team, in collaboration with PSI, published "Application of laser-induced breakdown spectroscopy to the analysis of algal biomass for induxrial biotechnology" in SpectrochimicaActa Part B, which uses LIBS technology and special The liquid sample laser chamber analyzes the accumulation of potassium, magnesium, calcium, sodium and other elements essential for algae and the accumulation of toxic heavy metals such as copper. There are two experimental design schemes, one is to measure the algae biofilm by using the vacuum sample laser chamber, and the other is to use the special liquid sample laser chamber to analyze the microalgae target element in the liquid (see the figure below).

Top left: Schematic diagram of biofilm measurement and analysis scheme; left lower panel: Schematic diagram of algal suspension measurement and analysis scheme design;

Right: Biofilm pulsed laser ablation hole

In recent years, CEITEC laser spectroscopy laboratory researchers have conducted a series of studies on liquid elemental analysis, and are at the forefront of the world in the field of elemental analysis of LIBS liquids (including aqueous suspensions), providing a variety of optimal solutions. The following figure shows the scheme for analyzing heavy metal elements (copper) in water:

4. Nanomaterials

Nanotechnology is a hotspot in today's materials technology, where Quantum dots (QDs) and their applications (such as quantum dot markers for life sciences, cancer cell imaging, etc.) are considered to be the most promising nanoparticles. In these applications, QDs must be accurately detected and their spatial distribution measured qualitatively and quantitatively. The current detection method is complex, time-consuming and expensive. The CEINEC/Atomtrace laser spectroscopy laboratory uses LIBS technology to treat different doses and different pH cadmium (Cd). The QDs solution was injected onto the filter paper, and the spatial distribution of QDs was measured and analyzed. It provided an important technical application scheme for the rapid detection of QDs by using LIBS technology.
