Abstract
In recent years, sulfur-containing nanomaterials and their derivatives/composites have attracted much attention because of their important role in the field of biosensor, biolabeling, drug delivery and diagnostic imaging technology, which inspires us to compile this review. To focus on the relationships between advanced biomaterials and biosensors, this review describes the applications of various types of sulfur-containing nanomaterials in biosensors. We bring two types of sulfur-containing nanomaterials including metallic sulfide nanomaterials and sulfur-containing quantum dots, to discuss and summarize the possibility and application as biosensors based on the sulfur-containing nanomaterials. Finally, future perspective and challenges of biosensors based on sulfur-containing nanomaterials are briefly rendered.
Highlights
As a by-product of oil refining and natural-gas purification, sulfur usually exists in the form of sulfide, sulfate or elementary substance in nature and is one of most abundant elements [1,2,3].Since the discovery of sulfur, research involving sulfur has always been at the center of scientific research topics
This paper provides a brief overview of recent researches on the applications of sulfur-containing nanomaterials, including metallic sulfide nanomaterials and sulfur-containing quantum dots in biosensors
Though many achievements have been obtained for biosensors based on sulfur-containing nanomaterials, there are still significant challenges that need to be solved
Summary
As a by-product of oil refining and natural-gas purification, sulfur usually exists in the form of sulfide, sulfate or elementary substance in nature and is one of most abundant elements [1,2,3]. We will summarize the most recent advances on the applications of applications of biosensors fabricated based on sulfur-containing nanomaterials and their composites biosensors fabricated based on sulfur-containing nanomaterials and their composites (Scheme 1). Speaking, the metallic sulfide nanomaterials include sulfur-containing quantum dots. We will briefly various kinds of metallic sulfide nanomaterials or sulfur-containing quantum dots and summarize introduce various kinds of metallic sulfide nanomaterials or sulfur-containing quantum dots and their synthetic approaches, respectively. We summarize the applications of biosensors nanomaterials or sulfur-containing quantum dots, respectively. The future perspectives and based on metallic sulfide nanomaterials or sulfur-containing quantum dots, respectively. The challenges of biosensors based on metallic sulfide nanomaterials or sulfur-containing quantum dots future perspectives and challenges of biosensors based on metallic sulfide nanomaterials or sulfurare briefly rendered.
