Article Synopsis
- A study examined six sorghum varieties with varying amylose levels to assess the structural and physicochemical characteristics of their starches and endosperm texture.
- Results indicated that as amylose content increased, the outer endosperm layer became less waxy and more corneous, with starch granules becoming more compact and showing fewer micropores.
- Amylose content affected various characteristics, showing negative correlations with granule size and certain starch properties, while positively correlating with different branch chain proportions, and these findings could inform potential applications in baijiu production.
The problems of multidrug-resistant bacteria and environmental pollution associated with the abuse of antibiotics call for effective antibiotic alternatives. Here, gold@silvergold alloy nanoflowers (Au@AgAu ANFs) with distinct atomic structures are first fabricated and then demonstrated for in vivo inhibition of bacteria. The Au@AgAu ANFs display high antibacterial activity against the model Gram-negative bacterium Escherichia coli, with a minimum inhibitory concentration value of 4.

Cy5-labeled DNA aptamer was embedded between the Au and Ag layers as a signal generator and target-recognition element, to fabricate uniform Au@Ag NSs with unexpected strong and stable SERS signals. The presented CAP can specifically bind to the DNA aptamer by forming an aptamer-CAP conjugate, and cause greatly decreased SERS signals of Au@Ag NSs.
