Genetic Silencing Technology Improves With Help From Quantum Dots
...siRNA) and semiconductor quantum dots (QDs), all enclosed by a proton-absorbing polymeric coating (aka proton sponge
Each quantum dot was surrounded by a proton sponge that carried a positive charge. Without any quantum dots attached, the siRNA's negative charge would prevent it from penetrating a cell's wall. With the quantum-dot chaperone,...
