AuPt nanoalloy with dual functionalities for sensitive detection of HPV16 DNA.

Human papillomavirus type 16 (HPV16), one of the high-risk types, is responsible for 53% of cervical cancers. The development of an early diagnostic approach with high sensitivity, low-cost, point-of-care testing (POCT) for HPV16 is urgent. In our work, a novel dual-functional AuPt nanoalloy-based lateral flow nucleic acid biosensor (AuPt nanoalloy-based LFNAB) was established with excellent sensitivity for detecting HPV16 DNA for the first time.

Facile preparation of a polypyrrole modified Chinese yam peel-based adsorbent: characterization, performance, and application in removal of Congo red dye.

In this study, Chinese yam peel (CYP) was modified with polypyrrole an polymerization method to remove Congo red from aqueous media. The prepared CYP-polypyrrole (CYP-PPy) composite was characterized using FTIR, SEM, TEM, XRD, TG and BET analysis. The performance of CYP-PPy towards the adsorption of Congo red (CR) was explored in batch mode.
