Prope huỳnh quang tỉ lệ dựa trên Dicyanomethylene-4H-Pyran cho Diazane và hình ảnh sinh học của nó
Tóm tắt
Một đầu dò huỳnh quang dựa trên ICT gần hồng ngoại mang tên LX đã được tạo ra thành công. LX có giới hạn phát hiện thấp tới 22,2 nm cho thấy độ chọn lọc tuyệt vời và độ nhạy cao với diazane. LX có khả năng phát hiện chọn lọc diazane so với các loài khác trong một khoảng pH rộng (3–10). Một thay đổi màu sắc rõ rệt của dung dịch từ màu vàng sang màu cam có thể được quan sát thấy, cho phép phát hiện bằng mắt thường. Cơ chế cảm biến đã được xác định hợp lý thông qua ESI-MS và các phép tính DFT. Ngoài ra, LX đã thành công trong việc hình dung diazane trong các tế bào sống và phát hiện diazane trong các mẫu nước.
