Chick wing bud mesenchymal cell micromass culture allows the study of a variety of developmental mechanisms, ranging from cell adhesion to pattern formation. However, many cells remain in contact with an artificial substratum, which can influence cyt

Ultrasound microbial cell disrupters operating at around 20 kHz are often physically large and, due to significant heating, can be unsuitable for small sample volumes where biochemical integrity of the extracted product is required. Development of a

An ultrasonic standing wave trap [Langmuir 19 (2003) 3635] in which the morphologies of 2-D latex-microparticle aggregates, forming a pressure node plane, were characterised has been applied here to different cell suspensions with increasing order of

It is shown that the magnitude of Rayleigh microstreaming convective drag on microparticles in water in a 3.2-MHz ultrasonic standing wave can be comparable to the lateral direct radiation force in the nodal plane (DRF 1 ) and can significantly influ

The ultrasonic standing-wave manipulation of suspended eukaryotic cells, bacteria and submicron latex or silica particles has been examined here. The different systems, involving plane or tubular ultrasonic transducers and a range of acoustic pathlen

Aggregation of suspended yeast cells in a small-scale ultrasonic standing wave field has been monitored and quantified. The aggregation effect is based on the acoustic radiation force, which concentrates the cells in clumps. The ultrasonic chamber em

Axially propagated ultrasound (APU) has been used to remove mineralized Proteus mirabilis biofilms from water-filled glass tubes. Pulses (30 s) of ultrasound at frequencies ranging from 350 to 20 kHz were applied to one end of the tubes and the exten

Continuous flow filtration of suspensions of eukaryotic cells by ultrasonic standing wave enhanced sedimentation has recently been reported. The filtration efficiency for Escherichia coli in such a filter has been characterized at frequencies of 1 an

Heterogeneous Chemistry Reviews. 3:443-475
This review is concerned with the physical chemistry of processes occurring during bioadhesion i.e. when living cells approach and contact other cells or when living cells approach and contact nonliving or solid surfaces. A good deal is known at pres
