Experimental and theoretical investigation of capillary flow with BSA and microbead suspensions
Bibliographic record
Abstract
The present study reports an investigation of capillary transport with a suspension of microbeads and biomolecules. Series of experiments are performed to deduce the concentration based surface tension and contact angle expression for microbead and biomolecule suspension. It is observed that, the microbead suspension restricts the spreading of the fluid front. Hence a decrease in the surface tension and an increase in the contact angle is observed as the concentration of suspension is increased. Different expressions for contact angle and surface tension depending on the range of the microbead concentrations are deduced. Theoretical model to predict the capillary transport in rectangular microchannel considering the change in physical and surface properties of the fluid is developed. The capillary transport in a microfabricated silicon microchannel is observed for fluid with and without microbead. Theoretical and experimental observations match quite well, whereas the quantitative difference in case of transport with microbead suspension is observed. Thus, the effect of suspension on the fluid properties can not be neglected in a capillary transport.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
