Lock and key colloids

Nature, 2010
New functional materials can in principle be created using colloids that self-assemble into a desired structure by means of a programmable recognition and binding scheme. This idea has been explored by attaching 'programmed' DNA strands to nanometre- and micrometre- sized particles and then using DNA hybridization to direct the placement of the ...

Three-Dimensional Lock and Key Colloids

Journal of the American Chemical Society, 2014
Colloids with well-defined multicavities are synthesized through the hydrolytic removal of silica cluster templates from organo-silica hybrid patchy particles. The geometry of the cavities stems from the originally assembled cluster templates, displaying well-defined three-dimensional symmetries, ranging from spherical, linear, triangular, tetrahedral,

Modular DNA-Origami-Based Nanoarrays Enhance Cell Binding Affinity through the "Lock-and-Key" Interaction.

Journal of the American Chemical Society, 2023
Surface proteins of cells are generally recognized through receptor-ligand interactions (RLIs) in disease diagnosis, but their nonuniform spatial distribution and higher-order structure lead to low binding affinity. Constructing nanotopologies that match

DK Lock: Dual Key Logic Locking Against Oracle-Guided Attacks

IEEE International Symposium on Quality Electronic Design, 2023
The semiconductor industry must deal with different hardware threats like piracy and overproduction as a result of outsourcing manufacturing. While there are many proposals to lock the circuit using a global protected key only known to the designer ...

Key-and-lock commodity self-healing copolymers

Science, 2018
Simple routes to self-healing Biology provides many routes for self-healing or repair, but this trait is hard to endow into engineering materials. Although self-repair has been demonstrated for some polymers, it usually required specialized monomers ...

Imaging Hg2+-induced oxidative stress by NIR molecular probe with "dual-key-and-lock" strategy.

Analytical Chemistry, 2020
Mercury (Hg) is considered as an extremely toxic heavy metal which is extremely harmful to both the human body and environment. In addition, Hg2+-induced oxidative stress also exerts a crucial role to play in pathophysiological mechanisms of mercury ...

Synthesis of ‘dual-key-and-lock’ drug carriers for imaging and improved drug release

Nanotechnology, 2020
In this work, a ‘dual-key-and-lock’ drug carrier was designed to respond to the tumor microenvironment (TME). A core–shell Fe-MOF@ZIF-8 was synthesized, with ZIF-8 as the shell (the first lock) to encapsulate catalase (CAT), and the Fe metal–organic ...
