This book is a lucid, straightforward introduction to the concepts and techniques of statistical physics that students of biology, biochemistry, and biophysics must know. It provides a sound basis for understanding random motions of molecules, subcellular particles, or cells, or of processes that depend on such motion or are markedly affected by it. Readers do not need to understand thermodynamics in order to acquire a knowledge of the physics involved in diffusion, sedimentation, electrophoresis, chromatography, and cell motility--subjects that become lively and immediate when the author discusses them in terms of random walks of individual particles.read more

Contribution of plus and minus end pathways to microtubule turnover.
TL;DR: In large animal cells with a centrosomally focussed array of MTs, turnover occurs by a combination of plus and minus end pathways, the plus end dominating at the cell periphery and the minus end dominating near the cell center.

Activity patterns of mobile epibenthic megafauna at an abyssal site in the eastern North Pacific: results from a 17-month time-lapse photographic study
TL;DR: In this paper, the authors deployed a time-lapse camera system at an abyssal site in the eastern North Pacific (Sta M; 34°50′N, 123°00′W; 4100 m depth) to monitor epibenthic megafaunal movements over the 17-month period from February 1990 through July 1991 Photographs, each covering approximately 20 m2, were taken every hour during this time span, except for the period from late October 1990 through mid-February 1991, when photos were takenevery 4 h Movements of the seven numer

Biosensor Systems in Standard CMOS Processes: Fact or Fiction?
Byungchul Jang,Arjang Hassibi +1 more
TL;DR: The compatibility of CMOS with various assaying techniques, detection modalities, and the possibility of fabricating their transducer structures on-chip is examined.

Characterizing T Cell Movement within Lymph Nodes in the Absence of Antigen
TL;DR: Comparisons of simulations with experimental data provide estimates of key parameters that characterize T cell motion in vivo, suggesting that at an intersection a T cell will turn onto a new fiber ∼50% of the time.

Biological shot-noise and quantum-limited signal-to-noise ratio in affinity-based biosensors
TL;DR: In this article, a Markov process is used to estimate the sensor inherent noise power spectral density (PSD) and response time of affinity-based biosensors and demonstrate that the SNR decreases as the dimensions are scaled down while the biosensor response speed increases, substantiating a fundamental trade-off between biosensor speed and accuracy.
