A novel estradiol-17β (E2) biosensor was constructed from poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons by modification of their outermost Au layer with an E2 binding 75-mer DNA aptamer. When E2 is not present in the solution, the aptamer forms a loose/linear structure that allows...

Progesterone (P4) is a vital steroid hormone involved in the reproduction cycle and necessary for maintenance of pregnancy in humans and animals. Monitoring P4 concentrations is required in various fields, such as dairy industry, environmental protection, and clinical laboratories. The current...

In this submission we fabricated a humidity-responsive polymer-based actuator by layering negatively charged poly(N-isopropylacrylamide)-co-acrylic acid microgels and positively charged poly(diallyldimethyl ammonium chloride) on top of a flexible plastic substrate. We show that the extent of the...
