Tóm tắt

Trong nghiên cứu này, vật liệu nano bạc (AgNPs) được tổng hợp bằng phương pháp khử hóa học với chất khử là natri citrate và chất bảo vệ là alginate. Các thông số ảnh hưởng tới quá trình tổng hợp nano bạc gồm nồng độ natri citrate, nồng độ bạc nitrate, nồng độ alginate và nhiệt độ của hệ phản ứng đã được nghiên cứu. Sự hình thành AgNPs, hình thái và cấu trúc của vật liệu sau khi tổng hợp được phân tích bằng quang phổ hấp thụ phân tử, hiển vi điện tử quét, hiển vi điện tử truyền qua và nhiễu xạ tia X. AgNPs có hiệu lực ức chế cao đối với nấm Pyricularia oryzae gây bệnh đạo ôn trên cây lúa.
