Scanning Kelvin Probe Force Microscopy for Secondary Phase Potentials

Check if the same lab product or an alternative is used in the 5 most similar protocols
The potentials (relative nobility potential) of secondary phases were measured by scanning kelvin probe force microscopy (SKPFM, Bruker Icon, Bruker, Billerica, MA, USA) in the tapping mode at room temperature (~25 °C) and a relative humidity of ~50%. A magnetic etched silicon probe was used to measure the relative Volta potential, with a bias potential of 5 V applied to the sample. The tip height is 100 nm, pixel resolution is 20 nm, and scan rate is 0.5 Hz. Prior to the SKPFM test, the samples were polished with diamond paste and alcohol. The samples were vacuum packed immediately after drying with cold air. The Volta potential differences were analyzed using NanoScope Analysis 2.0 software (Bruker, Billerica, MA, USA).

Characterization of SOD1 Fibrils by AFM

Check if the same lab product or an alternative is used in the 5 most similar protocols
SOD1 fibrils were produced as described above. Ten microliters of SOD1 fibril samples (~30 μM) were incubated on a freshly cleaved mica surface for 2 min, followed by rinsing three times with 10 μl of pure water to remove the unbound fibrils and drying at room temperature. The fibrils on the mica surface were probed in the air by the Dimension icon scanning probe microscope (Bruker) with ScanAsyst mode. The measurements were realized by using SCANASYST-AIR probe with a spring constant of 0.4 N/m and a resonance frequency of 70 kHz (Bruker). A fixed resolution (256 × 256 data points) of the AFM images was acquired with a scan rate of 1 Hz and analyzed by using NanoScope Analysis 2.0 software (Bruker).

A Bruker Multimode 8 HR scanning probe microscope (Bruker Nano Inc., Camarillo, CA, USA) was operated in peak force tapping mode with the capability of Quantitative Nanomechanics (PeakForce-QNM) in air mode conditions (24 ± 2 °C, 40% ± 5% RH). This advanced testing mode was used to examine the topographical and nanomechanical property changes of the collagen-peptide samples both before and after mineralization. Tapping mode etched silicon probes, type RTESPA 525-30 (Bruker Nano Inc., Camarillo, CA, USA) with a resonant frequency of about 518 kHz, were used to acquire images (1 μm × 3 μm and 5 μm × 5 μm) at scan rate of 0.5 Hz with 512 pixel/line resolution. The images of the samples were recorded using NanoScope 8.15 software and analyzed using NanoScope Analysis 2.0 software (Bruker Nano Inc., Camarillo, CA, USA).

Adsorption of Emulsion Droplets on Mica Substrate

Check if the same lab product or an alternative is used in the 5 most similar protocols
A 5 µL volume of the freshly prepared NFPh emulsion, prepared as described in Section 4.1, was dispensed onto freshly cleaved mica. Mica surface (0.15 mm thick, sized 15 × 15 mm, TipsNano, Zelenograd, Russia) was used as a substrate for non-covalent adsorption.
The emulsion droplet was incubated on the mica substrate surface for 10 min. Then, the substrate was washed with 1 mL of deionized water, which was obtained using a Simplicity UV system (Millipore, Molsheim, France). The washed substrate was dried in air and subjected to AFM scanning.
The AFM images of nanosized particles were obtained with a Dimension atomic force microscope equipped with an Icon scanner (Bruker, Billerica, MA, USA). The instrument is a part of the Avogadro unique research facility (http://avo.ibmc.msk.ru/ (accessed on 1 October 2023)). Scanning was carried out in the tapping mode. A short cantilever holder was used; the measurements were conducted in air. The images were recorded using the NanoScope 9.4 software (Bruker, Billerica, MA, USA). AFM images were processed using the standard NanoScope Analysis 2.0 software (Bruker, Billerica, MA, USA), Gwyddion 2.62, and Femtoscan Online software 4.8 (LLC Scientific and Production Enterprise “Center for Advanced Technologies”, Moscow, Russia; www.nanoscopy.net/en/Femtoscan-V.shtm (accessed on 6 May 2021)).

2M fibril samples (~17 μM) were then incubated on a freshly cleaved mica surface for 5 min, followed by rinsing three times with 10 μL of pure water to remove the unbound fibrils and drying at room temperature. The fibrils on the mica surface were probed in air by the Dimension icon scanning probe microscope (Bruker, Santa Barbara, USA) with ScanAsyst mode. The measurements were realized by using SCANASYST-AIR probe with a spring constant of 0.4 N/m and a resonance frequency of 70 kHz (Bruker).

All of the anhydrous solvents and chemicals were used as received from the commercial suppliers, unless otherwise indicated. Styrene (≥99%) (Lot: STBJ7184) and benzoyl peroxide (75%) (Lot: MKCG5941) were purchased from Aldrich (Poznan, Poland). 1H and 13C NMR spectra were recorded on Bruker (Billerica, MA, USA), AV-400 instrument (400 MHz). Chemical shifts (δ) were reported in parts per million (ppm). SEM images were obtained on a JEOL JSM-7400F scanning electron microscope (Akishima, Tokyo, Japan). AFM topographic images were obtained using a Nanoscope 9.7 Dimension ICON atomic force microscope (Bruker, Billerica, MA, USA) and the results were analysed using NanoScope Analysis 2.0 software (Bruker, Camarillo, CA, USA).
For antimicrobial assessments, tryptic soy broth (TSB) and Mueller Hinton broth (MHB) were purchased from Oxoid Ltd. (Basingstoke, UK), while yeast mold broth (YMB) was purchased from BD (Singapore). The broth solutions were prepared according to the manufacturer’s instructions. Gram-negative bacteria Escherichia coli (ATCC 8739), gram-positive Staphylococcus aureus (ATCC 6538), Gram-negative Pseudomonas aeruginosa (ATCC 9027), and fungi Candida albicans (ATCC 10231) were purchased from ATCC (Manassas, VA, USA) and re-cultured according to the suggested protocols.

A Bruker Dimension Icon Atomic Force Microscopy (AFM) system operating in tapping mode with TESPA-V2 tips was used to scan the nanocoils. A 50 µm wide field of view (FOV) was surveyed at a scan rate of 0.1 Hz to reduce tip and sample wear and improve image quality. The scans were imported into Bruker Nanoscope Analysis 2.0, sectioned, and exported as XZ plane height maps for further processing using Python. Turn width and spacing were determined using a partition threshold of 40 nm above the previous gap minimum. Mean turn width and spacing for all 14 turns and 13 gaps were plotted for comparison.

Average roughness (R A ) was calculated based on AFM images of non-coated and coated samples using NanoScope Analysis 2.0 image processing software (Bruker) on micrographs of 5 × 5 µm. R A measurements were performed on two different locations of three replicates per tested surface. To compare the roughness of non-coated and nanogel-coated pipe materials, Student's t-test was used.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
