Entropy-driven physical amplification in multivalent biosensing
Xiuyang Xia, Yuhan Peng, Ran Ni
Sensitive detection of low-abundance molecular targets is widely assumed to require enzymatic amplification, such as PCR, to achieve low detection limits. In amplification-free pla…
Designed self-assembly of programmable colloidal atom-electron equivalents
Xiuyang Xia, Yuhan Peng, Ka Ki Li +1
To unlock the potential for assembling complex colloidal "molecules", we investigate a minimal binary system of programmable colloidal atom-electron equivalents (PAE-EE), where ele…
A bond swap algorithm for simulating dynamically crosslinked polymers
Peilin Rao, Xiuyang Xia, Ran Ni
Materials incorporating covalent adaptive networks (CAN), e.g., vitrimers, have received significant scientific attention due to their distinctive attributes of self-healing and st…
Designing superselectivity in linker-mediated multivalent nanoparticle adsorption
Xiuyang Xia, Ran Ni
Using a statistical mechanical model and numerical simulations, we provide the design principle for the bridging strength () and linker density () dependent superselectivity…
