Fully room temperature and label free biosensing based on an ink-jet printed polymer microdisk laser
TLDR
In this article, a microdisk laser was fabricated using a low-viscosity hyper branched polymer FC-V-50 using ink-jet printing, and was surface modified at room temperature within a relatively short time compared to conventional methods.Abstract:
Materials with biomolecule-compatible functional groups are desirable for the fabrication of microdisk lasers used in bio-sensing applications. In this study, a microdisk laser was fabricated using a low-viscosity hyper branched polymer FC-V-50 using ink-jet printing, and was surface-modified at room temperature within a relatively short time compared to conventional methods. The carboxyl functional group of the FC-V-50 polymer was used for surface modification and biotinylation. The adsorption characteristics of the microdisk laser were evaluated using bovine serum albumin, avidin, and streptavidin. This study reports the first demonstration of label-free biosensing using the FC-V-50 polymer-based microdisk laser.read more

Role of edge inclination in optical microdisk resonator for label-free sensing
D. Gandolfi,Fernando Ramiro-Manzano,Francisco Aparicio Rebollo,Mher Ghulinyan,Georg Pucker,Lorenzo Pavesi +5 more
TL;DR: By numerical simulations, it is shown that the microdisk thickness is critical to yield a high figure of merit for the sensor and that edge inclination should be kept as high as possible and that bulk-sensing figures of merit as low as 1600 RIU−1 (refractive index unit) are feasible.

Intrinsic viscosity of polymers: From linear chains to dendrimers
TL;DR: In this paper, a simple theory for the intrinsic viscosity of polymers of arbitrary architectures, based on a partially permeable sphere model, is presented, which introduces two phenomenological functions, the drainage function κ(r) and the drag function ξ(r), which are determined by the density profile, as a mean-field description of the multi-body, long-range and accumulated effects of the hydrodynamic interactions.
