Chemically characterizing the cortical cell nano-structure of human hair using atomic force microscopy integrated with infrared spectroscopy (AFM-IR)

Figure 2 from A. P. Fellows et al “Chemically characterizing the cortical cell nano-structure of human hair using atomic force microscopy integrated with infrared spectroscopy (AFM-IR)”: AFM-IR data obtained from a human hair cross-section (approx. 300 nm thick) showing (a) a schematic structural representation of the cortical cell (b) average spectra corresponding to each observed region (macrofibril and Ext-matrix) (c) AFM height map and (d)-(l) IR-intensity maps recorded in contact mode across a 2.5 × 2.5 μm region of the surface at a number of different infrared frequencies corresponding to contributions observed in the spectra (each shown above the corresponding image) for a representative fibre section. NANOSENSORS AdvancedTEC ATEC-CONTAu tip view AFM probes were used.

The structure of hair fibres has been the focus of much research over the last century with several techniques used to investigate their structure. *… Read More »Chemically characterizing the cortical cell nano-structure of human hair using atomic force microscopy integrated with infrared spectroscopy (AFM-IR)

Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments

Figure 3 from “Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments” by Miguel Cantero et al.: Treatment of TGEV with IGEPAL 0.2% (A). Topographical images before (left) and after (right) IGEPAL treatment (B). Profiles traced over the particles before (black) and after (blue) the treatment. The time interval between images was ~30 s (C). Height distribution of TGEV particles before (black) and after (blue) treatment (n = 103). Counts taken from the distribution curve were normalized for comparison. The peak shifts from the value of the intact particle height to the height of the cores. NANOSENSORS uniqprobe qp-BioAC AFM probes were used for the atomic force microscopy measurements.

Successful airborne transmission of coronaviruses through fluid microdroplets requires a virion structure that must withstand harsh natural conditions. * Because of the strict biosafety requirements… Read More »Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments
