"protocol": "The BP sheets are synthesized by a modified liquid exfoliation technique, where 20 ppm BP sheets are dispersed in aqueous solution and exposed to an NIR laser (808 nm, 1.0 W cm^-2) for 10 minutes.The micro-sized BP flakes were prepared by mechanical exfoliation from the bulk crystal using scotch tape and transferred to a Si/SiO2 wafer. The BP sheets were prepared by a modified liquid exfoliation technique. Briefly, the BP crystals were dispersed in NMP with an initial concentration of 1 mg/mL and ground to fine powders. The dispersion was sonicated in an ice bath for 70 hours using a power of 300 W and centrifuged at 4000 rpm for 10 minutes. The supernatant containing the BP sheets was decanted gently and centrifuged for another 10 minutes at 7000 rpm. The precipitate was collected and resuspended for subsequent experiments. A certain amount of agarose powders (4 wt%) was dispersed in deionized water under mechanical stirring at 90°C for 30 minutes and stored in a 4°C refrigerator for 30 minutes to obtain the agarose hydrogels. BP Hydrogel was prepared by mixing the agarose solution with BP sheets (20 ppm). B P&C A P Hydrogel was obtained by dispersing 2 mg CAP nanoparticles (approximately 200 nm in diameter) into the BP Hydrogel solution and prepared by the same method as described above."
