The size and ζ-potential were measured by dynamic light scattering using a Zetasizer Nano model ZEN3600 (Malvern Panalytical, Malvern, UK). All measurements were performed in triplicate. Three different batches of each system were evaluated. For the size measurements, the samples were diluted 20-fold with distilled water and, for ζ-potential, 10 mM of sodium chloride solution was used at the same dilution. High resolution scanning electron microscopy images were acquired using an Extra-High Resolution Scanning Electron Microscope Magellan 400L (Thermo Fisher Scientific, Waltham, MA, USA, former FEI), equipped with a tunable diode laser (TLD) detector. The 10 µL samples were diluted 20-fold with water, as above, and placed on copper grid support films, formvar/carbon, 400 mesh, Cu (Ted Pella, Inc., Redding, CA, USA). The images were scanned at 5 kV acceleration voltages.

The AgBr-NP@CTMAB particles were incorporated at 0.25, 0.50 and 1.00% (wt/wt) with the PMMA powder and mixed manually under constant agitation for 10 min to obtain an adequate particle distribution. Then, the mixture powders were dispersed in the MMA liquid and immediately mixed together under stirring by the same operator. The powder (g)-to-liquid (mL) ratio was maintained as recommended by the manufacturers.27 (link) After homogenization, the mixture was injected into a stainless-steel mold during the plastic phase.28 (link) After low-temperature polymerization (55±5°C, 30 min, Multicure, Vertex, Zeist, Netherlands), specimens were polished with abrasive papers 600 up to 1000 grit under water cooling. Then, the specimens (10.0 mm×10.0 mm×2.0 mm) were scrubbed with water and ultrasonically cleaned for 30 min before immersion in PBS 52±2 h at 37 °C.29 (link) The morphology of the modified PMMA-based specimens was analyzed by a stereomicroscope (Magellan 400L; FEI Co) before testing.

Unless otherwise noted, all of the reactions were conducted in a dry reaction flask made of glass under argon or nitrogen at atmospheric pressure. The water content of the solvent was confirmed with a Karl-Fischer Moisture Titrator (MKC-210, Kyoto Electronics Company) to be <100 ppm. Distilled water was further purified with Millipore Milli-Q. Bath sonication for dispersion of CNHs was carried out on a Honda Electronics WT-200-M instrument. Powder X-ray diffraction (PXRD) measurements were carried out on Rigaku SmartLab. Dynamic laser light scattering (DLS) was carried out on a Malvern Zetasizer Nano ZS machine. pH measurement was carried out by using pH paper (UNIV, Toyo Roshi Co.

The affinity of the polyMA-Glu-BP NPs to calcium ions
was evaluated by incubating coral fragments (5.55 mg) with NIR fluorescent
polyMA-Glu-BP NP dispersion (200 μL, 0.5 mg/mL) for 2 h. The
solution was removed, and the coral was washed three times with 1
mL of DDW. As a reference, coral fragments were treated similarly
with the NIR fluorescent control NP dispersion (200 μL, 0.5
mg/mL) and DDW. The coral fragments were evaluated by a fluorescent
microscope Olympus BX 60 Qimaging EXi Blue QCcapture X-64. In addition,
the coral fragments were then attached to a stab with carbon glue
tape, coated with carbon in vacuum, and analyzed with a high-resolution
scanning electron microscope (FEI, Magellan 400L).

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.
