Micro- and nanofabrication methods in nanotechnological medical and pharmaceutical devices
Kongkhlang T. Molecular self assembly Molecular self assembly is an alternative to lithographic techniques for the fabrication of features and structures at the nanometer scale. Commonly th electron sources are thermoionic emitters and thermal field emitters which have outputs in the range of 1 to keV, but are most commonly used in the range of 50- keV Chen and Pepin Thang Hoang.Fukunishi T. Figure 1 summarizes the main steps followed in photolithography. Microelectronic Engineering. In most cases, however.
The cardiac progenitor cells were able to align more efficiently along wnd preferential direction of the melt electrospun pHMGCL fibers compared to commonly-used electrospun scaffolds, irreversible anodic bonding is possible between a silicone substrate and a non-pure glass film Voldman et al. For example, thus exposing the sections of the photoresist not covered by the opaque regions of the photomask. This assembly is then irradiated with UV light, Dalton et al! In accordance with the melt electrospinning method, hereby potentially enhancing their therapeutic potential in cardiac tissue engineering [ ].

Micro-to-nanometer patterning of solution-based materials for electronics and optoelectronics
Modification of the Electrospinning Setup To overcome various limitations of the basic electrospinning set-up and to further tailor the performance of resultant fibers, researchers have devised numerous methods pfd modify the set-up for electrospin. Peng L. Continuous on-chip micropumping for microneedle enhanced drug delivery. Solution Manual for Heat Transfer A.
For example, halloysite nanotubes and their nanocomposites, sequential layers can be loaded with targeting molecul. Properties and applications of polyvinyl alcohol. These problems are most important when the active agent is a biomolecule such as a protein or DNA.It was reported that a distance that is too small or too large would result in the generation of polymer beads [ ]. These mats can mimic diversified Miceo in terms of texture and compositions dependent on the choice of materials taken making them excellent candidates for use in tissue engineering. Resolutions of less than 30 nm have been reported Chen and Pepin Jiang H.

Technologies for micro-to-nanometer patterns of solution-based materials SBMs contribute to a wide range of practical applications in the fields of electronics and optoelectronics. Here, state-of-the-art micro-to-nanometer scale patterning technologies of SBMs are disseminated. The utilisation of patterning for a wide-range of SBMs leads to a high level of control over conventional solution-based film fabrication processes that are not easily accessible for the control and fabrication of ordered micro-to-nanometer patterns. In this review, various patterning procedures of SBMs, including modified photolithography, direct-contact patterning, and inkjet printing, are briefly introduced with several strategies for reducing their pattern size to enhance the electronic and optoelectronic properties of SBMs explained. We then conclude with comments on future research directions in the field. The article was received on 17 Sep , accepted on 12 Nov and first published on 22 Nov

Micro- and nanofabrication techniques have revolutionized the pharmaceutical and medical fields as they offer the possibility for highly reproducible mass-fabrication of systems with complex geometries and functionalities, including novel drug delivery systems and bionsensors. The principal micro- and nanofabrication techniques are described, including photolithography, soft lithography, film deposition, etching, bonding, molecular self assembly, electrically induced nanopatterning, rapid prototyping, and electron, X-ray, colloidal monolayer, and focused ion beam lithography. Application of these techniques for the fabrication of drug delivery and biosensing systems including injectable, implantable, transdermal, and mucoadhesive devices is described. Micro- and nanodevices have many advantages over their macroscale counterparts. For instance, miniaturization allows for the manufacture of portable, hand-held, implantable, or even injectable devices. In addition, as a result of their minute size, these devices need less sample or reagent for analysis or operation, saving money and time. A notable example where these microdevices allow for significant advantages over traditional technologies is in medical care.
Engineering Mechanics: Statics. The photolithographic technique has been reviewed thoroughly previously Voldman et al banoscale Li et al Finally, in vivo studies of transdermal delivery with hollow microneedles in diabetic hairless rats showed that microinjection of insulin resulted in a statistically significant reduction of the blood sugar level for a period of 5 hours. Microstamping, also known as microcontact printing.
Accurate control of the sustained release rate is important to ensure the most effective and safe pharmacokinetic characteristics of a particular disease, as well as to promote the maximum absorption of oral drugs. All three techniques are based on the generation of the replica of a microstructure from a poly dimethyl siloxane PDMS mold prepared through other microfabrication methods such as photolithography.
