Soft Matter. 2016 Aug 21;12(31):6526-35. doi: 10.1039/c6sm01095d. Epub 2016 Jul 15.

We introduce a new type of hybrid material: a nanostructured elastomer covered by a hard photoactive metal-oxide thin film resembling the exoskeleton of insects. It has extreme water repellency and fast self-recovery after damage. A new fabrication method for...

Granzyme B mediated function of Parvovirus B19-specific CD4(+) T cells.

Clinical & translational immunology

Kumar A, Perdomo MF, Kantele A, Hedman L, Hedman K, Franssila R.
PMID: 26246896
Clin Transl Immunology. 2015 Jul 03;4(7):e39. doi: 10.1038/cti.2015.13. eCollection 2015 Jul.

A novel conception of CD4(+) T cells with cytolytic potential (CD4(+) CTL) is emerging. These cells appear to have a part in controlling malignancies and chronic infections. Human parvovirus B19 can cause a persistent infection, yet no data exist...

Coating of nanoporous membranes: atomic layer deposition versus sputtering.

Journal of nanoscience and nanotechnology

Grigoras K, Airaksinen VM, Franssila S.
PMID: 19504916
J Nanosci Nanotechnol. 2009 Jun;9(6):3763-70. doi: 10.1166/jnn.2009.ns64.

Nanoporous anodic alumina membranes and silicon samples with plasma etched nanopores have been coated with zinc oxide or gold layer using atomic layer deposition (ALD) or sputtering, respectively. In the case of ALD process, the precursor pulses were extended,...

Stroboscopic supercontinuum white-light interferometer for MEMS characterization.

Optics letters

Hanhijärvi K, Kassamakov I, Heikkinen V, Aaltonen J, Sainiemi L, Grigoras K, Franssila S, Hæggström E.
PMID: 22627543
Opt Lett. 2012 May 15;37(10):1703-5. doi: 10.1364/OL.37.001703.

We used a supercontinuum-based scanning white-light interferometer to characterize the oscillation of a MEMS device. The output of a commercially available supercontinuum light source (FiberWare Ilum II USB) was modulated to achieve stroboscopic operation. By synchronizing the modulation frequency...

Platinum Recovery from Industrial Process Solutions by Electrodeposition-Redox Replacement.

ACS sustainable chemistry & engineering

Halli P, Heikkinen JJ, Elomaa H, Wilson BP, Jokinen V, Yliniemi K, Franssila S, Lundström M.
PMID: 30416892
ACS Sustain Chem Eng. 2018 Nov 05;6(11):14631-14640. doi: 10.1021/acssuschemeng.8b03224. Epub 2018 Sep 20.

In the current study, platinum-present as a negligible component (below 1 ppb, the detection limit of the HR-ICP-MS at the dilutions used) in real industrial hydrometallurgical process solutions-was recovered by an electrodeposition-redox replacement (EDRR) method on pyrolyzed carbon (PyC)...

Thiol-ene micropillar array electrospray ionization platform for zeptomole level bioanalysis.

The Analyst

Lipponen K, Tähkä S, Sikanen T, Jokinen V, Tatikonda A, Franssila S, Kostiainen R, Kotiaho T.
PMID: 28617495
Analyst. 2017 Jul 10;142(14):2552-2557. doi: 10.1039/c7an00544j.

A micropillar array electrospray ionization (μPESI) platform fabricated from thiol-enes with 56 individual polyethylene glycol coated μPESI chips for bioanalytical mass spectrometry is introduced. Bioanalysis capability is shown by measurement of a protein, a protein digest and a cell...

Controlled communication between physically separated bacterial populations in a microfluidic device.

Communications biology

Osmekhina E, Jonkergouw C, Schmidt G, Jahangiri F, Jokinen V, Franssila S, Linder MB.
PMID: 30271977
Commun Biol. 2018 Jul 20;1:97. doi: 10.1038/s42003-018-0102-y. eCollection 2018.

The engineering of microbial systems increasingly strives to achieve a co-existence and co-functioning of different populations. By creating interactions, one can utilize combinations of cells where each population has a specialized function, such as regulation or sharing of metabolic...

Hyalinizing trabecular adenoma: A misnomer for a peculiar tumor of the thyroid gland.

Endocrine pathology

Sambade C, Franssila K, Cameselle-Teijeiro J, Nesland J, Sobrinho-Simões M.
PMID: 32138392
Endocr Pathol. 1991 Jun;2(2):83-91. doi: 10.1007/BF02915330.

We describe the clinical, histological, immunohistochemical, and electron microscopical features of 9 tumors fulfilling the criteria of the so-called hyalinizing trabecular adenoma (HTA) of the thyroid. Six tumors had the characteristic histology of HTA throughout, whereas in the remaining...

Sacrificial Layer Technique for Releasing Metallized Multilayer SU-8 Devices.

Micromachines

Tatikonda A, Jokinen VP, Evard H, Franssila S.
PMID: 30572576
Micromachines (Basel). 2018 Dec 19;9(12). doi: 10.3390/mi9120673.

The low fabrication cost of SU-8-based devices has opened the fields of point-of-care devices (POC), µTAS and Lab-on-Chip technologies, which call for cheap and disposable devices. Often this translates to free-standing, suspended devices and a reusable carrier wafer. This...

Lab-on-a-chip reactor imaging with unprecedented chemical resolution by Hadamard-encoded remote detection NMR.

Angewandte Chemie (International ed. in English)

Telkki VV, Zhivonitko VV, Selent A, Scotti G, Leppäniemi J, Franssila S, Koptyug IV.

The development of microfluidic processes requires information-rich detection methods. Here we introduce the concept of remote detection exchange NMR spectroscopy (RD-EXSY), and show that, along with indirect spatial information extracted from time-of-flight data, it provides unique information about the...

Nature offers exciting examples for functional wetting properties based on superhydrophobicity, such as the self-cleaning surfaces on plant leaves and trapped air on immersed insect surfaces allowing underwater breathing. They inspire biomimetic approaches in science and technology. Superhydrophobicity relies...
