Superselectivity as a Receptor-Fluctuation Response
Xiuyang Xia
Superselective multivalent binding enables sharp receptor-density discrimination in targeting and sensing, but what its logarithmic response measures microscopically remains unclea…

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…
