“…The vapor-phase deposition of polymers, which is an environmentally friendly, solvent-free, and material independent method, offers unique advantages over conventional solventbased techniques. [21][22][23][24][25] In this way, polymers can be conformally deposited in a controlled manner onto substrates with non-planar geometries like paper and unwanted impurities, degradation of the underlying layer, and changes in the mechanical/chemical features associated with the use of solvents can be precisely eliminated. 24,25 Fig.…”

“…[21][22][23] By utilizing this approach, non-planar substrate geometries which have micro-and/or nano-scale features can be readily coated, displaying uniform polymer thickness over the geometric features present in the substrate. 24,25 Meanwhile, unwanted impurities, degradation of the underlying layer, and undesirable effects of de-wetting and surface tension related to the use of solvents can be precisely eliminated. [21][22][23][24][25] Recently, Gupta and co-workers have demonstrated polymer deposition on paper substrates using an initiated-chemical vapor deposition (i-CVD) technique.…”

Given their simplicity and functionality, paper-based microfluidic systems are considered to be ideal and promising bioassay platforms for use in less developed countries or in point-of-care services. Although a series of innovative techniques have recently been demonstrated for the fabrication of such platforms, development of simple, inexpensive and versatile new strategies are still needed in order to reach their full potential. In this communication, we describe a simple yet facile approach to fabricate paper-based sensor platforms with a desired design through a vapor-phase polymer deposition technique. We also show that the fabricated platforms could be readily employed for the detection of various biological target molecules including glucose, protein, ALP, ALT, and uric acid. The limit of detection for each target molecule was calculated to be 25 mg dL(-1) for glucose, 1.04 g L(-1) for protein, 7.81 unit per L for ALP, 1.6 nmol L(-1) for ALT, and 0.13 mmol L(-1) for uric acid.

“…Recently, various groups have been reporting on utilizing CVD processes for the application of different functional polymer films. [6,28] Single-step methods for CVD functional polymers [6] A number of single-step methods to deposit functional polymers using different CVD approaches are listed in Table 2 [6] Combining these approaches with the CCS ® technology used in PVPD enables fully scalable implementations.…”

Novel solutions for thin film layer deposition for organic materials

Innovative systems for carrier-gas enhanced vapor phase deposition of organic layers offer advanced methods for the precise deposition of complex thin-film layer stacks. The approach inherently avoids potential short-comings from solvent-based polymer deposition and offers new opportunities. The process operates at low pressure (thus avoiding complex vacuum setups), and, by employing AIXTRON's extensive experience in freely scalable solutions, can be adapted to virtually any production process and allows for R&D and production systems alike.Deposition of organic layers and stacks recommends the approach for a wide range of organic small molecule and polymer materials (including layers with gradual change of the composition), for conductive layers, for dielectric layers, for barrier systems, for OLED materials, and surface treatments such as oleophobic / hydrophobic coatings.With the combination of other vapor phase deposition solutions, hybrid systems combining organic and inorganic materials and other advanced stacks can be realized.

“…Additionally, different deposition approaches such as atomic layer deposition (ALD) in combination with molecular layer deposition [10][11][12][13][14], and all PE-CVD developed multilayers have been reported in literature [15][16][17][18]. Coclite et al [19] reported on the deposition of multilayers based on organosilicon chemistry, in which the inorganic barrier layer is deposited by means of PE-CVD and the organic interlayer is deposited by means of initiated-CVD (i-CVD) [20][21][22]. Recently, Spee et al reported on the deposition of SiN x /poly-glycidylmethacrylate/SiN x , where the inorganic layer was deposited by hot wire chemical vapor deposition (HWCVD) and the organic layer by i-CVD [4].…”
