Characterization of the Alg-Bi2S3@BSA scaffolds. FESEM images of (a) Alg scaffold (Scale bar = 100 μm), (b) Alg-Bi2S3@BSA (0.25%) (scale bar = 200 μm), (c) Alg-Bi2S3@BSA (0.5%) (scale bar = 100 μm), and (d) Alg-Bi2S3@BSA (1%) (scale bar = 200 μm). (e) SEM image of Alg-Bi2S3@BSA (1%) scaffold (white dots are Bi2S3@BSA nanoparticles, scale bar = 100 nm). EDS spectrum of (f) Alg-Bi2S3@BSA (0.25%), (g) Alg-Bi2S3@BSA (0.5%), and (h) Alg-Bi2S3@BSA (1%). (i) EDS elemental mapping of the Alg-Bi2S3@BSA (1%) scaffold (scale bar = 100 μm). (j) Compressive moduli of scaffolds (Alg and Alg-Bi2S3@BSA (1%), respectively).
