Opt Express
. 2009 Jun;
14(21):9786-93.
PMID: 19529370
Recent work has indicated the potential of light to modify the growth of neuronal cells. The two reported studies however, were performed on two independent optical set-ups and on differing...

PMID: 19529110
Laguerre-Gaussian (LG) beams are important in optical micromanipulation. We show that optically trapped microparticles within a monochromatic LG beam may lead to the formation of unique intensity patterns in the...

Jess P, Garces-Chavez V, Smith D, Mazilu M, Paterson L, Riches A, et al.
Opt Express
. 2009 Jun;
14(12):5779-91.
PMID: 19516747
Raman spectroscopy permits acquisition of molecular signatures from both cellular and sub-cellular samples. When combined with optical trapping we may interrogate an isolated cell reducing extraneous signals from the local...

Opt Express
. 2009 May;
12(11):2560-5.
PMID: 19475094
Optical guiding of microscopic particles is studied and compared for femtosecond and continuous wave Bessel light beams. We confirm that optical guiding is an average power effect and observe no...

16(21):17007-13.
PMID: 18852810
Optically assisted transfection is emerging as a powerful and versatile method for the delivery of foreign therapeutic agents to cells at will. In particular the use of ultrashort pulse lasers...

Phys Rev Lett
. 2008 Oct;
101(14):143601.
PMID: 18851526
We create extended longitudinally optically bound chains of microparticles with the use of counterpropagating "nondiffracting" light fields, the so-called Bessel beams. The beam homogeneity and extended propagation range allow the...

Opt Express
. 2008 Jun;
16(6):3712-26.
PMID: 18542466
Near-field optical micromanipulation permits new possibilities for controlled motion of trapped objects. In this work, we report an original geometry for optically deflecting and sorting micro-objects employing a total internal...

. 2003 Oct;
91(9):093602.
PMID: 14525181
We observe the spinning and orbital motion of a microscopic particle trapped within a multiringed light beam that arises from the transfer of the spin and orbital components of the...

Opt Lett
. 2003 Apr;
28(8):657-9.
PMID: 12703932
We examine the properties of interfering high-order Bessel beams. We implement an experimental setup that allows us to realize these interferograms, using interfering Laguerre-Gaussian beams and an axicon. We demonstrate...
