“…200 A number of developments based on new cantilevers and new AFM-based temperature measuring techniques have been stated in recent years. 43,45,[201][202][203][204][205][206][207][208][209][210] Sadat et al 23 have reported a thermometric AFM-based technique which does not require integrated temperature sensors in AFM probes. The technique allows direct mapping of topography and temperature fields of metal surfaces with $0.01 degree temperature resolution and <100 nm spatial resolution.…”

Non-invasive precise thermometers working at the nanoscale with high spatial resolution, where the conventional methods are ineffective, have emerged over the last couple of years as a very active field of research. This has been strongly stimulated by the numerous challenging requests arising from nanotechnology and biomedicine. This critical review offers a general overview of recent examples of luminescent and non-luminescent thermometers working at nanometric scale. Luminescent thermometers encompass organic dyes, QDs and Ln 3+ ions as thermal probes, as well as more complex thermometric systems formed by polymer and organic-inorganic hybrid matrices encapsulating these emitting centres. Non-luminescent thermometers comprise of scanning thermal microscopy, nanolithography thermometry, carbon nanotube thermometry and biomaterials thermometry. Emphasis has been put on ratiometric examples reporting spatial resolution lower than 1 micron, as, for instance, intracellular thermometers based on organic dyes, thermoresponsive polymers, mesoporous silica NPs, QDs, and Ln 3+ -based up-converting NPs and b-diketonate complexes. Finally, we discuss the challenges and opportunities in the development for highly sensitive ratiometric thermometers operating at the physiological temperature range with submicron spatial resolution.

“…This kind of microscopy has been used to detect metal nanoparticles (Raschke et al 2003) for biomolecular recognition. Kim et al (2007) demonstrated the usage of dark-field detection with a rather large bead (> 2 μm) for stretching DNA or RNA detecting enzymatic activity. The scattering from metal beads was so intense that it could even be used for high speed measurements as was shown for studying the flagella rotary motor at frequencies as high as 300 Hz.…”

Printed on acid-free paper PrefaceFood nanoscience and nanotechnology are emergent disciplines that have grown enormously in the last years due to the attractive properties that a number of foodrelated materials have at the nanoscale. Understanding basic principles of such properties constitutes the basis for building a robust knowledge base for developing products with improved and novel characteristics.Understanding fundamentals of food nanotechnology represents a huge challenge for universities, industries and the public sector. The complex mechanisms involved in the research, development, production and legislation of food nanoproducts are studied under multi-and inter-disciplinary scopes. Bearing this in mind, this book was conceived.This book aims to contribute to basic and applied knowledge on these fields by presenting recent advances in selected topics of food nanoscience and nanotechnology, and is divided into a total of 17 chapters. The first chapter presents an overview to the field; the following chapter discusses general techniques for studying foodrelated nanomaterials, followed by six chapters on specific techniques for preparing food nanomaterials while the next contribution on dispersed systems illustrates this important and vast field. The book continues with three chapters on food nanocomposites, including those for packing purposes, and two chapters on advanced aspects of food nan...

We report herein development of a novel glass micropipette thermal sensor fabricated in a cost-effective manner, which is capable of measuring steady thermal fluctuation at spatial resolution of ∼2 μm with an accuracy of ±0.01 °C. We produced and tested various micrometer-sized sensors, ranging from 2 μm to 30 μm. The sensor comprises unleaded low-melting-point solder alloy (Sn-based) as a core metal inside a pulled borosilicate glass pipette and a thin film of nickel coating outside, creating a thermocouple junction at the tip. The sensor was calibrated using a thermally insulated calibration chamber, the temperature of which can be controlled with an accuracy of ±0.01 °C, and the thermoelectric power (Seebeck coefficient) of the sensor was recorded from 8.46 to 8.86 μV/°C. We have demonstrated the capability of measuring temperatures at a cellular level by inserting our temperature sensor into the membrane of a live retinal pigment epithelium cell subjected to a laser beam with a focal spot of 6 μm. We measured transient temperature profiles and the maximum temperatures were in the range of 38–55 ± 0.5 °C.
