Key Points:
- We examined effects such as droplet size and PFC core on bubble dynamics and material viscoelastic properties within three different hydrogels, each of different concentrations.
- Gelatin hydrogels reveal concentration-dependent impacts on bubble expansion and material elasticity.
- Embedding PFC droplets in gelatin increases internal pressure, resulting in higher equilibrium radius and continuous bubble growth during quasi-static evolution.
- Similar trends are observed in fibrin and polyacrylamide matrices, with differences in bubble behavior attributed to matrix properties and droplet presence.
- Droplet size exhibits minimal impact on bubble expansion during inertial dynamics but influences quasi-static evolution, with larger droplets leading to continuous growth beyond 60 seconds.
- The core composition of PFC droplets significantly affects bubble behavior, with higher boiling point droplets exhibiting higher maximum expansion and faster quasi-static dissolution rates.
Research Overview:
Perfluorocarbon (PFC) droplets represent a novel class of phase-shift contrast agent with a promise in applications in biomedical and bioengineering fields. PFC droplets undergo a fast liquid-gas transition upon exposure to acoustic or optical triggering,
offering a potential adaptable and versatile tool as contrast agent in diagnostics imaging and localized drug delivery vehicles in therapeutics systems. In this paper, we utilize advanced imaging techniques to investigate ultra-high-speed inertial dynamics and
rectified quasi-static (low-speed) diffusion evolution of optically induced PFC droplet vaporization. The study sheds light on the intricate interplay between droplet characteristics, matrix properties, and multi-timescale bubble dynamics, offering valuable insights into their behavior within biomimetic hydrogels.
Methodology:
The data are the output of the microcavitation experimental setup, which generates and records single, sub-millimeter laser-induced cavitation (LIC) bubble events at 1 million fps in soft hydrogels and materials using a combination of single 4 ns pulses of a user-adjustable,
frequencydoubled Q-switched 532 nm Nd:YAG laser (Continuum Minilite II, San Jose, CA), an ultra-high-speed imaging camera (HPV-X2; Shimadzu, Kyoto, Japan) and a low-speed imaging camera (FLIR).
