Optical microsphere resonators working in the near‐ and mid‐infrared regions are highly required for a variety of applications, such as optical sensors, filters, modulators, and microlasers. Here, a simple and low‐cost approach is reported for batch fabrication of high‐quality chalcogenide glass (ChG) microsphere resonators by melting high‐purity ChG powders in an oil environment. Q factors as high...
Silk fibroin (SF) microspheres were produced by salting out SF solution via the addition of potassium phosphate buffer solution (K2HPO4–KH2PO4). The morphology, size and polydispersity of SF microspheres were adjusted by changing the molecular weight (MW) distribution and concentration of SF, as well as the ionic strength and pH of the buffer solution. Changing the conditions under which the SF fiber...
