Streptavidin-Biotin Binding is Intrinsically Non-Cooperative, but Experimental Artefacts Can Induce Apparent Positive Cooperativity
Malavika Kayyil Veedu, Eléonore Martenne Duplan, Saurabh Rai +2
The biotin-streptavidin interaction is a key component of nanobiotechnology, yet the nature of its cooperativity remains a debated question. Here, we introduce a label-free spectro…

Single Nanoparticle Dynamics in Opto-Thermal Tweezers: Resolving the Temporal Resolution of Depletion Force Trapping
Jinchao Chen, Robert Talla Kontchou, Saurabh Rai +4
Optothermal tweezers enable the manipulation of a wide range of nano-objects through optically induced depletion forces. Despite significant advances, the temporal dynamics of opto…
