“…In the case of Mohs micrographics surgery, LIBS elemental mapping may be applied to a sectioned tissue to rapidly create a map showing the cancer and normal tissue regions. Although elemental mapping of solid samples by LIBS has been investigated by many researchers previously, [13][14][15][16] LIBS elemental mapping of biological samples is relatively new. Recently, Motto-Ros et al published a number of papers for LIBS imaging of biosamples.…”

Surgical excision (Mohs micrographic surgery) is the standard procedure to treat a melanoma, in which an in situ histologic examination of sectioned skin is carried out repeatedly until no cancer cells are detected. The possibility to identify melanoma from the surrounding skin by femtosecond laser-induced breakdown spectroscopy (fs-LIBS) is investigated. For experiments, melanoma induced on a hairless mouse by injection of B16/F10 murine melanoma cell was sampled in the form of frozen tissue sections as in Mohs surgery and analyzed by fs-LIBS (λ ¼ 1030 nm, τ ¼ 550 fs). For analysis, the magnesium signal normalized by carbon intensity was utilized to construct an intensity map around the cancer, including both melanoma and surrounding dermis. The intensity map showed a close match to the optically observed morphological and histological features near the cancer region. The results showed that when incorporated into the existing micrographic surgery procedure, fs-LIBS could be a useful tool for histopathologic interpretation of skin cancer possibly with significant reduction of histologic examination time.

The metallurgical industries are very important for social development. In order to improve the metallurgical techniques and quality of products, the real-time analysis and monitoring of iron and steel manufacturing processes are very significant. Laser-induced breakdown spectroscopy (LIBS) has been studied and applied for the contents measurement of iron and steel. In this paper, the remote open-path LIBS measurement was studied under different sample temperature, lens to target distance (LTD), sample angle conditions to clarify its online measurement features. The 3D profile measurement system of parallel laser beam fringes projection was also developed to measure the sample profile at different sample temperature. The measurement results demonstrated the robustness of remote open-path LIBS system and 3D profile measurement system. However, the correction is necessary to enhance the detection ability of LIBS online measurement. In order to improve the precision and accuracy of real-time elemental measurement, an innovative co-axial laser beam measurement system combining LIBS and 3D profile techniques is proposed to automatically adjust the focus unit and measure the sample components. The further study of this promising method will be developed for online application of iron and steel manufacturing processes. KEY WORDS: laser-induced breakdown spectroscopy; 3D profile; remote measurement; iron and steel manufacturing processes.

“…There are various advantages of LIBS technique, such as no sample preparation, low sample consumption, multi-element simultaneous monitoring, fast detection, real-time analysis, etc. [9][10][11] LIBS technique shows the potential for fast detection and real-time analysis, which has attracted many scholars to study the application in the steel-making process. Aragón et al 12) used LIBS method to detect the carbon content of molten steel samples in a laboratory induction furnace and proved that this method can be used for the direct determination of alloy melt composition.…”
