“…The reported results can be particularly interesting for experiments with tightly focused beams [101], for the generation of novel polarizations in CR [81], in optical micromanipulation [80,142,143], mode conversion between Heremite-Gauss-like beams and Laguerre-Gauss-like beams [76] and in super-resolution imaging [85]. It is also promising the generation of polarization-tunable potentials to inject, extract and ma-nipulate ultra-cold atoms [55,144].…”

“…The low intensity regions have been formed using, for instance, interference of multiple laser beams, partially spatially coherent optical vortices or laser beams affected by optical aberrations. The suitability of an optical bottle for particle trapping and manipulation has been confirmed in experiments with atoms [170,171] and absorbing particles [86,143,172,173].…”

“…[172,174]. The photophoretic force has been used as a speckle trap [169], to trap biological samples [175,176], combined with engineered vortex beams as a tractor beam [86,143] and demonstrated to also depend on the polarization of the illuminating source [143,177]. …”

A mis padres, hermanos, sobrinos y a Raquel AcknowledgmentsTot té un principi i un final i aquest serà el punt final a una etapa de la meva vida la qual estic segur que d'aquí uns anys, quan miri enrere, veuré que ha estat probablement la que ha tingut una major rellevància tant a nivell personal com científic. Quan vaig acabar la carrera no tenia gaire clar quin camí seguir però vaig tenir la sort de parlar amb qui ha estat el meu director de tesi, el Jordi, qui em va guiar i va posar tota la seva confiança en mi des del primer moment. Em va oferir un tema original i es va aventurar a dirigir una tesi amb una forta vessant experimental, tot un atreviment venint d'un teòric! Quan vaig començar el Màster, si m'haguessin dit on he arribat 5 anys després mai m'ho hauria cregut i, Jordi, tu tens gran part de culpa de tot això. Moltes gràcies per haver confiat en mi des del primer dia, per haver-te mostrat sempre tan orgullós de tot el que he fet, per haver estat sempre disponible i per ajudar-me i animar-me quan he passat moments durs durant aquest anys. M'has ensenyat a ser un bon científic, a moure'm dins aquest món, a creure em mi i a ser una millor persona. Mai t'estaré prou agraït per tot això i per haver sigut tan proper amb els teus cotilleos, converses de futbol, política, noies, etc. dinant al bar. Has estat com un pare per a mi (bueno, un germà gran, que tampoc ets tan vell per a ser Mompare :P). Si el Jordi ha estat el meu pare en la ciència, el Yury ha estat el meu gurú científic. Mai he trobat una persona tan pacient, que sàpiga tant de qualsevol tema i amb tanta dedicació com tu. M'has ensenyat a ser riguròs, a tenir un mètode, la importància de estar al dia de tot el que es fa en el cap d'estudi, a programar, i un llarg etcètera. En resum, m'has ajudat a donar-me forma a mi mateix com a científic i a tenir perseverança en el que faig. Tot això sense oblidar que per a mi ets un gran amic! Seguidament, també he donar les gràcies al Todor, una de les persones més enèrgiques que conec i amb més passió per la ciència. Tu vas iniciar tot el tema de la refracció cònica al nostre grup i has demostrat que ets realment qui més coneix de cristalls i del fenomen en si. Si no hagués estat per tu, no podríem haver començat res d'això i no podríem haver explotat el fenomen ni una quarta part del que hem fet. Ets un exemple per tenir sempre un somriure a la cara i per aquesta iii iv força que et fa tirar endavant tots els teus projectes. També vull donar les gràcies a altres companys del Grup d'Òptica, començant per la Verònica, que va passar de ser una "professora de la carrera" a ser el meu ideal de constància i l'esforç. Ets un exemple professional a més a més d'una persona molt més propera i alegra del que pot semblar a primera vista. A Ramón también le tengo que agradecer su ayuda y su disponibilidad a lo largo de estos años, su paciencia cuando ha tenido que soportar mis imitaciones y su alegría y naturalidad en todo momento. Amb el Francesc també he compartit molts bons moments, sobretot a les diverses activit...

“…In addition, the metasurface could exhibit an anisotropic or bianisotropic response to provide micromanipulation control through polarization adjustment [33,46]. For example, it should be possible to control the degree at which microparticles are pushed or pulled by simply changing the polarization of the incident Gaussian beam [12,13]. This would allow for the arbitrary manipulation and sorting of small particles with a single beam.…”

“…Therefore, the vast majority of light never actually interacts with the particle of interest. Many other methods of pulling particles towards a source using light [13], sound [14], or currents in fluids [15] have recently been proposed, but they require a strong interaction between the particle and the surrounding media. Optical conveyor belts can also move objects towards a light source over significant distances [16,17].…”

Propagation invariant beams that pull objects towards a light source are commonly known as tractor beams. Here, an efficient linearly polarized tractor beam with improved stability is introduced. The beam consists of a superposition of TE and TM polarized Bessel beams of orders m = +1 and m = −1. It is shown that this beam can stably pull a wide range of dielectric microparticles arbitrarily long distances, independent of ambient conditions. Next, a straightforward method of generating these high performance beams is proposed. A Si metasurface transforms an incident linearly polarized Gaussian beam into the desired tractor beam. Full-wave simulations demonstrate that it is possible for this simple geometry to pull a polystyrene sphere a distance equal to the non-diffracting range of the Bessel beam. The simplicity of the setup and the robust performance of the proposed tractor beam significantly enhance the ability to manipulate matter with light.

Optical forces, generally arising from changes of field gradients or linear momentum carried by photons, form the basis for optical trapping and manipulation. Advances in optical forces help to reveal the nature of light–matter interactions, giving answers to a wide range of questions and solving problems across various disciplines, and are still yielding new insights in many exciting sciences, particularly in the fields of biological technology, material applications, and quantum sciences. This review focuses on recent advances in optical forces, ranging from fundamentals to applications for biological exploration. First, the basics of different types of optical forces with new light–matter interaction mechanisms and near‐field techniques for optical force generation beyond the diffraction limit with nanometer accuracy are described. Optical forces for biological applications from in vitro to in vivo are then reviewed. Applications from individual manipulation to multiple assembly into functional biophotonic probes and soft‐matter superstructures are discussed. At the end future directions for application of optical forces for biological exploration are provided.
