Shining a tightly-focussed but low-powered laser beam on an absorber dispersed in a biological fluid gives rise to spectacular growth of dendritic patterns. These result from localized drying of the fluid because of efficient absorption and conduction of optical energy by the absorber. We have carried out experiments in several biologically relevant fluids and have analysed patterns generated by different types of absorbers. We observe that the growth velocity of branches in the dendritic… 



Laser-Driven Accelerated Growth of Dendritic Patterns in Liquids

We report a scheme for very significantly accelerated growth of dendritic patterns in organic, inorganic, polymeric, and biological liquids, using laser power as low as a few hundred microwatts in

Bright visible emission from carbon nanotubes spatially constrained on a micro-bubble.

Emission of broadband light in the spectral range 500 nm - 900 nm from single walled carbon nanotubes (SWNTs) in a liquid environment upon irradiance by a very low power, continuous-wave laser source in a tweezers setup is reported.

Pattern selection in two-dimensional dendritic growth

Abstract We present an analytical treatment of the problem of pattern selection in a fully non-local symmetrical model of dendritic crystal growth. Simplifications of mathematical equations are based

Optical-tweezer-induced microbubbles as scavengers of carbon nanotubes

A modified optical tweezers set-up has been used to generate microbubbles in flowing, biologically relevant fluids and human whole blood that contains carbon nanotubes (CNTs) using low power, infrared, continuous wave laser light and it is observed that proximate CNTs are driven towards the focal spot where, on encountering the microbubble, they adhere to it.

Dendrites, Viscous Fingers, and the Theory of Pattern Formation

There has emerged recently a new theoretical picture of the way in which patterns are formed in dendritic crystal growth and in the closely analogous phenomenon of viscous fingering in fluids. Some

Pattern formation and morphology evolution in Langmuir monolayers.

Frequency histograms of unstable wavelengths are consistent with the linear-instability dispersion relation of classical free-boundary models and a possible explanation of why Langmuir monolayers present this kind of nonequilibrium growth patterns is presented.

Pattern selection in fingered growth phenomena

Abstract A variety of non-equilibrium growth processes are characterized by phase boundaries consisting of moving fingers, often with interesting secondary structures such as sidebranches. Familiar

Multiscale random-walk algorithm for simulating interfacial pattern formation.

A novel computational method is presented to simulate accurately a wide range of interfacial patterns whose growth is limited by a large-scale diffusion field and can be used to simulate three-dimensional dendritic growth in a previously unreachable range of low undercoolings that is of direct experimental relevance.

Purity assessment of single-wall carbon nanotubes, using optical absorption spectroscopy.

A simple protocol for purity assessment of laser and arc-discharge SWNTs has been established that can be extended to other synthetic types and diameter distributions, and has enabled corroboration of rapid assessment procedures, such as absorbance peak maxima ratio and Beer's law analysis.
